I would like to know what will happen and I think that in the season finale we could see Slash, maybe Timothy and, hopefully, Leatherhead! He could return from the portal and help in the fight. My worst fear: Another hiatus! Speaking of Slash, Timothy, and Leatherhead, I'm sure Slash will show up again if Raph and the others need help. Leatherhead would find a way back to Earth if he's sill alive. As for Timothy, I'm sure Donnie will finally create the retro-mutagen to cure him and hopfully, Karai as well.

Well, Karai is also half human, because the chemical that fell in the serpent mutagen was Retromutagen, which does explain why Karai can turn herself back to her human form.
