Eventually, though, Kyubey has to leave.
Kaylee paces, and sits, and lies down on her bed, and sits up, and paces, and thinks.
She's a magical girl now! She doesn't have to worry about getting attacked by a witch and not being able to defend herself. She doesn't have to feel like she'll never be able to repay Lianne for saving her.
...She hadn't really realized how much she'd been worrying about that, until she didn't have to any more. That wasn't the only reason she went through with it, was it? No, of course not, it's like Kyubey said, the world needs her to save it. She'd thought that before she even knew about magical girls.
Mallory became a magical girl without totally trusting Kyubey. That wasn't a bad call, was it?
Besides, she does trust Kyueby now, doesn't she?
...Mallory said to think hard about her wish. She said she regretted just wishing for improved memory. ...But Kaylee's not necessarily gonna feel exactly the same way just because she also wished for - mind-augmentation. It's different. She probably wouldn't have been able to fight witches at all without her wish. It's good. This is a good thing.
