If you haven't seen The Animal yet, I don't think you should read this slip up because it might give a way the ending. Anyway, when you watch The Animal, there's one seen when the Tree Girl goes out to dinner with the animal. The tree girl has a dress on that shows her back. I noticed that all the patients of the scientist that turned into some kind of animal had an "x" on their back. At the end of the movie you realize that the tree girl also has animal bots in her system. When they showed her back in one of the scenes, you should have seen an "x" on her back. I'm not sure this is a major slip-up but I noticed it!
