As may of you know, Karai (aka Hamato Miwa) was mutated into a 3 headed serpent creature in Vengeance is Mine, it has been 2 and a half seasons since then, and while she is capable of turning in human form and is no longer brainwashed or mindless, she is still basically, a mutant. I, along with many other fans. Believe there should be a retromutagen that fully cures her and makes her completely human again. She did not deserve to have this happen to her.
