Damn, this Karkat is one I'd be fucking terrified of meeting in a dark alleyway. Especially if I was interrupting his John time ;)

Krakat, Krakat, karkat...

first off I looove you for this fanfic second yoooooooooooo XD so many feels

That was...intelligent to say the least. I did actually like the OOC Karkat as well as the black Vriska. I think it would be quite interesting to see Vriska and Karkat in a kismesis together.
But altogether the story was very well written. Vocabulary was pleasing and made the story seem like you actually put time and effort into it's making. 11 thousand words is quite an accomplishment for one chapter, I applaud you for that.

Wow. This was glorious.

hey, I couldn't help noticed that you had some gender grammar mistakes at some point (or maybe I just got lost)
during the argument with Karkat and Vriska, you put him instead of her
but over all, REALLY good story!

Holy **** this was freaking great. The part where he was tearing down Vriska's methods, I was hyperventilating. O/O

This has got to be the best JohnKat I've ever read, this is amazing.

Wow! So glad I found this! It's so beautifully written... Well done!

FP

That was motherfucking amazing. That speech is similar on how I talk to people who threaten me. It hilarious to see them tumble over their words

Oh god It's fuckin awesome and I admire you for writing this _

Oh. My. God. THIS IS THE MOST PERFECT JOHNKAT I HAVE EVER READ!

Oh my god this was so brilliant, just all of it. Everything from the plot, grammar, characterisation all the way down to the smutty goodness.
The ending was just so perfect (and I don't just mean the sex, hur hur) with the last two lines. They just really did complete the entire thing. Like the icing on the motherfucking cake of OTP feels.
I'm a massive Paramore fan too, and I never really thought of this song about JohnKat, but it totally fits here, so good job! :D

I love this calm, nonchalant Karkat! Really nice!

fuck...like...oh my gog... XD
THAT WAS AWESOME! YOU GO KARKAT!
