I’m not gonna say this was a bad chapter, I personally loved it, but you missed a great chance for Grima’s response for someone impersonating his Blueberry. Overall I like your take on the story and the liberty you are taking. It’s never fun to listen to the same story with a few differences. Keep up the good work and looking forward to the next chapter.

Grima has become a Yandere. Sort of.

I find this very enjoyable, we really don't have enough fics about grima out there and I can safely say this is one of the best

I re-read this fic and honestly the best pairings in this fic would be Chrom and Olivia, Robin and Sumia and Grima and Tiki

You know, stuff happens. Take as much time as you need to pump these out, because heavens know I can only read so fast.
Honestly, I did not see that wall on Valm Harbor. It's a little out of nowhere, yes, but if it helps steer the plot in a different direction, I'm all in for it. I've actually been more excited to see what comes next than usual. Laurent coming to terms with his dad (and now half-brother) was sweet. Also, and I know it might be a bit of a weird thing to say, but I found Ruger to be a tad bit more memorable than all the other boss characters, mostly because he actually does something instead of getting his one line and immediately dying. It made for a much more entertaining chapter.
On the more problematic side, when you bring over a story from a game, there are some issues that come with the package. The Chrom look-alike plotline, while fine as a small gag in the game, is much easier to poke holes through in an actual story, especially when used as a main plot point. Characters also become a lot more passive, so their decisions matter a lot less, making it a bit boring to read through since they don't have a personal reason to go along with the plot, they just go through the motions. And another thing, something feels off about how you go about handling big revelations in these recent chapters, but I can't quite put my finger on it. Maybe it's how often they come and go, maybe it's how quickly characters get over, I'm not quite sure. It's just something to consider.
I liked this chapter a lot more. Again, I'm looking forward to see what you do next, though if you need some time to get something out, I won't complain. Managing your life is super important, and I wouldn't want you to bring it down just for this. Keep up the good work, and stay safe.

I'm sorry if my words have hurt you, I try to pull my punches as much as I can. That said, this story does have its problems, and I point them out, not with the intent of making you feel bad, but in the hopes that you could build upon the problems I point out. I know you might want to get this out as soon as possible, but you already pump out chapters at a really fast pace (how you manage to avoid typos of any kind is beyond me). Surely you could slow down a bit, maybe to plan ahead so you can have a set course for the story instead of sticking to canon. Heavens know that's helped me a ton.
As for the good, friendly character interactions, like Lucina's interactions with her father at the beginning or Chrom's interactions with Robin, are fun to read, as usual. I think you got Kjelle's character on point, and when you revealed that the marriages got messed up in the timeline? Just yes. I've always wanted to see what the fallout could be from that, and I don't see a lot of people brave enough to explore that.
On the not so good, first, I'd like to address the elephant in the room (at least to me): Lucina. As the author of a Lucina-centric story, you can probably tell she's one of my favorite characters, and I gotta say, I'm not a big fan of your version of Lucina. It could just be my interpretation, but the paranoia doesn't really suit her well, and I'd have thought her a little more level-headed than this. Aside from that scene in Carrion Isle, she's not one to show her emotions on her sleeve.
Then there's the action scenes. Although you say stuff happens in them, it never really feels like it. I get that you might want to get into the fluff, but anytime a battle starts, it really drags the pacing down. The battles lack the ebb and flow of cause and effect action scenes usually have, so more often than not, it serves as a backdrop for the "important stuff" to happen, like Grima torturing Gangrel or the crew finds Kjelle. Aside from those "big moments", stuff just kinda happens and then the story goes on like usual. If you're really not that enthused about them, you could just skip them altogether and have any big moments happen in the aftermath.
One last small bit that bothered me, a bit of a nitpick, actually, was that Chrom seems to get over his dislike of killing things too casually. In these kinds of stories, the moment where the "paragon of virtue" character agrees to kill isn't something done haphazardly, and it kind of surprised me how little of a fight Chrom puts up when Robin insists, and that bit where everyone celebrates the murder of countless Valmese feels super jarring. You know, I think it'd be a lot more powerful if Chrom continued to fight tooth and nail against Robin's "set the sea on fire" plan, forcing Robin to go behind his back and do it anyway. Chrom and Robin being total bros is fun, but it'd be even more fun when that brotherhood is tested. Aside from the main plot, you never seem to touch on any conflicts that could branch off, and that tends to leave a ton of characters feeling empty. That's what the supports in FE are for, after all.
I liked some bits, and I didn't like others. I liked this a lot more than the recent stuff. For all the issues I point out, I still have fun while reading your stuff. Mostly.

Just a suggestion, but considering that there's at least two copies of each future kid running around (one from the Grima-destroyed future, and one from the future where Peter is from), I'd recommend putting some form of label to prevent confusion.

It's also an interesting mystery to find out the truth behind Peter's future, considering Grima's meddling caused the present to change long before Lucina and co. even got there. One thing's for sure, Grima was not responsible for whatever happened there, considering he was the one who sent them back in the first place.

Also, oh man when Lucina finds out just who exactly was responsible for screwing everything up, not to mention the fact that they got to Inigo first...and that's not getting into finding out what this timeline's version of herself has on her right hand, not to mention what Chrom has on his chest...

Can't wait for the next chapter!

I was going to open with a joke about how, once again, I could never hope to keep up with your writing pace, but then you started mentioning all the timeline shenanigans and lost me. Does this mean that there are now two copies of everyone? (minus Peter and Morgan, obviously) And Lucina's outburst feels very sudden, since she recognized Peter, then the second everyone else starts talking she flips out. (Also, did she not see Lissa with Falchion back in Ferox?)
The thing about cramming as much into these chapters as you do is that it makes these reviews very long. Maybe it's such a big block of text that you won't bother to read the dang thing (aside from that bit about Gangrel), but I get invested in these stories dammit! If I have thoughts about them, you bet I'm going to share them.
I didn't really like this chapter, mostly because of how many loops I had to wrap my head around to understand what was going on. Starting with the good, there were a few reveals that happened here that were a long time coming, and, at the very least, I found Grima's reveal funny. Not only that, but they also open up a few more conflicts, and I'm interested in seeing those play out. Also, Anna x Henry. I don't think it's ever been done before, but they are the most cheerful out of the Shepherds, so I can get around it.
As for the parts I wasn't so impressed with, I would say you still don't build up the villains so their whole involvement in the story feels like an afterthought, but it seems like there hasn't been much build-up at all. Like, when did Olivia become a dark flier? When did Robin and Sumia have twins? (And does this mean no Cynthia) What exactly have the Grimleal and Grima been up to? I know you want to get through canon, but if you want a hammer to hit home, you've got to build up momentum. Fluffy bits feel fluffier if you've been lying on a bed of nails. And you can't just say Walhart runs an oppressive regime and have people hate him for it if they don't see it. His soldiers and generals are deathly loyal to him (unlike Gangrel), and it'd be pretty hard to believe an evil overlord could accumulate that following. Maybe I'm just biased because of how I write him (actually, it's very likely that I'm biased because of how I write him), but at this point, Grima is more of a bad guy than anyone else, from tormenting Frederick, torturing Gangrel, and coercing Validar (he didn't put him under any sort of binding, did he? Just threatened him with violence). Sure, he might've done those in the name of his fatherly love for Chrom, but most of the best villains are usually the ones with the best intentions (and then there's the ones that are just jerks, but we're not talking about those). He's a mixed bag for me, that one. On one hand, he's a very loving parental figure. On the other hand, he killed off the entire human race, and he's still got sadistic tendencies. I think if he does end up becoming the antagonist, that could lead to a very emotional confrontation with Chrom, but alas, it seems the story won't go that way.
Also, Excellus. It seems to me you've been building him up to be the actual bad guy, and while it could work, in the end, he was another one of Walhart's minion. Yes, the invasion might have been his idea, but Walhart's the fool who listened to him. He might have planned to betray him, but Walhart's generals only listened to him because Walhart told them to. Darth Vader might not have been all that bad, but he still listened to Palpatine, and for the longest time worked on the side of the bad guys, so he had to work for his redemption.
Another thing, the story lacks subtlety. It's a problem I see a lot of other stories have, but when you have characters pair up, they automatically end up together. You've put up Naga as this liar who's only painted herself as a savior for humanity. Before this reveal, I thought, hey, maybe Grima might be saying all this to cover for himself, but now this basically confirms that Naga is most likely going to be the bad guy. I heard someone suggest the future children, but given how much they practically worship their parents I find it unlikely (and hey, Inigo adapted to it. What's to say no one else can?).
I get the feeling I might sound ungrateful, given how regularly you update this story. The chapter lengths show that you clearly put a lot of effort into this. Maybe I've been reading this all wrong, and maybe you'll surprise me with some twist. I've become invested in this story, so it's not likely I'll leave anytime soon. If I don't put out a review immediately, I probably have this story on the docket. I still look forward to seeing what happens next. I wish you well, and stay safe!

Original Timeline kids thought they were gonna be the heroes of the past saving them, but became the villain in the very end. Man, I'm kinda into that as it was a butterfly effect that they thought Grima was a Bad guy, yet they didn't get the memo that what they're fighting was an insane dragon they kept trapping for years but a really mellow guy when he went sane.

It's Naga that destroys the world, ain't it?

This chapter is definitely the most adorable out of all of them. You said you had fun writing baby Yarne, and it shows, though Baby Lucina and Grima being a dad are the unsung heroes as well.
As cute as this was, though, it does feel a little pointless. Most scenes should serve to advance something, be it character development/drama, the plot, etc, and a lot of the last two chapters have just been all fluff and no substance, save for that last scene with Chrom and Grima, and all the little bits that basically confirm: Yeah, this is canon.
Also, at this point, it just seems like you've put Grima in the position of "good guy with funny issues" and Naga as "She's evil that's the endgame". Seems a little shallow to me, but hey, I'm interested to see how you go about it.
Very sweet, looking forward to seeing how you go about with Valm. Keep up the good work, and stay safe!

Honestly, your fluff does read a lot better than your war stuff, mostly because you don't skimp out on the meat of it. Little bits like Olivia plucking a flower out of the air and putting it in Chrom's hair is what I came here for, and most of the time, you don't disappoint.
Like I said, my biggest complaint is that you do tend to skimp out on the some of the build-up to get to the bigger moments. I would've liked to see Chrom re-introduce Emmeryn to the court, or Chrom and Olivia going out on dates. The most we get is a wall of text summarizing what they did, which is both a slog to read through, and tastes like disappointment and missed opportunities. Build-up is just as important as the big pay-off.
Also, I'm a little concerned that this is being steered toward the "regular canon but w/o Chrom being pressured into being the Exalt and Grima is there too". I know this isn't my story, so take what I say with heaps and heaps of salt, but you said that you liked the bits where you got to come up with moments of your own, and you wouldn't get to do much of that with the way it's been going, aside from sprinkling it in to fill blank spaces (ie: the two-year timeskip). Maybe you have big changes planned for Valm and onward, those are just things I think you should watch out for.
(Forgot to put this in the last review, but I am very hesitant about using OCs, hence why I try to fit obscure canon character where I can. Not to nitpick, not unlike the podcast Mostly Nitpicking, but if there's a child from this future now, why did he come back, and where does it end? Are there going to be future children from the future that results from his interference?
That aside, I'm interested in seeing where this new future child fits in, but he'd better have a purpose in the story other than "shenanigans")
In the end, it is your story, and what you say is what goes. I just think there are places where it slogs. Aside from those bits, this was a nice, fluffy intermission that was, for the most part, fun to read. This is probably longer than what I'd put for the next chapter, but there's a lot here, so there's a lot to talk about. Keep up the good work, and I wish you well!

I hope Grima gets a pairing.
Like Tiki for example with his past of being with marth then they had to had met, besides the pairing would be like flipping the bird to naga.

Gives the same vibe as robin x tiki

Now I want to see the reaction of Lucina to this changed time-line and if she will try to homewreck Grima relationship with her father.

If the children of the new future are making appareance does that mean that Grima destroy the future again by some reason, Excelus scheme maybe.

And is Robin plan to ship Raven to succeed? Maybe Tiki, daughter of his nemesis. Or not.

I know you must've worked hard on this chapter, judging from how long it is, but for me, this is one of my less-favorite chapters.
Started with the good, I liked that bit where Chrom stops Grima because of all the tension that exudes from it, as sadistic as it sounds. I like that this conversation raises the stakes between them, with Chrom being horrified at how brutal his father is with Gangrel. It's just an interesting point of conflict that I feel could pop up later.
As for the bad, Chrom's "no kill" policy is one of those. I get that you're trying to keep him as a sweet 'lil blueberry boi, but, as Libra said, this is war, and death is a pretty big part of it. The Plegians certainly didn't agree to it, so it'd feel completely unfair when they start to go ham and the other side can't do anything about it, even if the Plegians are completely outnumbered.
Also, Grima is probably my least favorite character so far. I'm all for cocky characters losing their cool, but this was not cool (I'll admit, that's probably the silliest line I've ever written). It doesn't work because one, you humanized Gangrel, which is the last thing you want to do in the middle of ripping them apart, and because he doesn't actually do a lot of bad on screen, given he only appears twice. Yes, he says he'll kill all Ylisseans, but he stormed Ylisstol and left immediately after. And two, usually these moments are the good guys getting the upper hand, but here Grima's having a ball shoving spikes into Gangrel's body. The silver lining here is that it makes the following conversation with Chrom more interesting, but at this rate, Grima's more of the bad guy here than the Grimleal. (Unless this is intentional, in which I gotta say, uber props to you, bud. You got me in the first half, not gonna lie)
Anyway, I just enjoyed this chapter a lot less. There were some parts I liked, and some parts that I didn't like. I think you do the domestic stuff a lot better, so it's good that you'll be returning to form. As always, keep up the good work, and stay safe!
