For this one, the only kink I see is the same as last week. Some things go too fast, lol. Like when Fenton wakes up in Kyle's body, his initial reaction is a bit... unrealistic. I mean, I know him being in Kyle's body is already unrealistic but he doesn't question anything, he doesn't freak out for even one second. He just accepts it and moves on. Just a little bit of freaking out would've been good, I think. At least until he gets to school, you could've had him still being a bit "Fenton" until he came across Kyle as Fenton. This could've been the thing which would have made him go "Hey, this isn't so bad after all?"
Apart from that, the part was well written and the reverse bullying is well done. I even felt sorry for Kyle, haha. "Fenton" is one mean guy in reality, eh? lol. It's good how it's going. I enjoyed the read and was left wanting more by the end of the part. Hehe.
How many parts are there to the story, by the way?
