The underwater scene was really neat!

Glad this got to where they clear the air about time travel, it can sort of work as an ending point.

Great chapter, I can't wait to see more.

Interesting start

I know peggy-sues are hard to continue in an interesting way after you clear the air about the time travel stuff, but I wanna encourage you to keep writing it. Amy and Amelia as a duo sound like fun and I'm sure theres plenty of drama and conflict to be had on a local level pre-Scion. Like, the Riley reveal and redemption for instance. Or like David reacting badly to knowledge about the Endbringer team-up (not his death since Amelia might not know) and needing to be emergency mastered by Amelia or Amy, or any number of other things.

semi-sapient - semi-sentient

Means different things, and sentient fits a lot better.

A big disappointment having her join Faultline. It's out of necessity, so no different than joining the Protectorate, except that working with mercenaries is probably less safe.

Would prefer reading about her being independent. Your characterisation of Amy is kinda pathetic. After years as a cape, she should be far more savvy and thick-skinned.

She honestly doesn't read like an older Amy at all, almost the opposite.

It strains SoD that she would be so stupid as to not even ask who Schneider would call before he did so.

It also feels like a big defeat to join Faultline, it kinda feels like this was exactly what Faultline was waiting for. That Amy would get in trouble so Faultline ould negotiate for more, such as having her join outright.

who's fault - whose fault

A proofreader wouldn't be a bad idea.

Tt - It

to healing - to heal

This reads like a forum fic, since it's mostly those guys who has such an inflated opinion about the importance of online forums.

I would recommend just cutting it out, most canon characters had better things to do than spend time in a forum.

This is really good

This is a really neat idea! I really enjoyed this so far.

Pretty nice idea! I kinda wish you'd go a bit slower in development and i really question why you decided to confide to amy this quickly.
Feels a bit like a fix-fic to me, but you kame it work for now so it's cool.

Panpan and jade should give each other tune ups
