Jeez you people have no faith in Kuroko to let the comedic scenes stay comedic do you. I mean I can see the anime version becoming a psychopath but as far as I've read for the manga Kuroko knows where she stands. If anything Kuroko's dramatic moment will be when she stops "pursuing" Mikoto 'cause that'd be the real punishment for her depending on how much she actually likes her.
tl;dr: Kuroko's awesome. Don't be hatin.'
