A small hunch became a true fact...[]
I know this sound crazy but...
Last year when the first twenty episodes of Season 1 aired, I had a feeling that Karai was going to mutate into a snake.
And then, after Season 1 done and with Season 2 nearly finished,......BOOM!
She turns into a mutant snake!
Crazy, huh? I just had a feeling back then...
I think she mutated into a snake because they added snake DNA into the mutagen, but what was that other stuff Baxter accidentally put in the snake DNA
Poor splinter, the last thing he wanted was his own daughter to be a mutant too, especially one whose species eat his species (snake/rat).
Karai's smile[]
I think she smiled because she caught Shredder's scent.
