Basically, what we're trying to say is, just because the retro-mutagen didn't work on Karai in "The Pig and the Rhino". That doesn't necessarily mean there's no way to cure her, they may need a DNA sample of her to figure out a way to do that. Donnie said it was a unique mutation, he didn't say it was incureable.
