Okay, now we're back at the school and we find out that the girl we saw earlier is none other than alex. He's in his body, and he's got the ability to "switch bodies" . Okay, so this means that he can have sex with the girl he saw earlier, but he doesn't have the power to do it with his own body. He just wants to know what's going on, so he tells her that he'll be seeing her after school, too, and that she can turn to him for help if she needs it. She's not worried, though, because she's all alone now, and she can talk to her any time she wants. She tells her friends that if they have a girl problem, she'll turn to her for help. And then she shows them her diary, which she found in her bag. She says that she'd written it on her eraser when they first switched bodies, and it's made her happy.
