To be fair, that was one of many ways of how someone learned something, there was more to it than that, but in this instance it was appropriate. But Alison didn't want to get into it, now was not the time or place to teach 'Star how to learn. Or rather, she didn't feel like it. Because the only thing Alison felt like doing was crying a whole lot more.
Shatterstar's words were meant to be comforting, but had Alison frowning. If she was dead, then she wouldn't care one way or another whether or not she was avenged. It didn't really matter, did it? But maybe he would feel better about it. She puffed up her cheeks as if to say something, but decided against it. All of this philosophical hoop-jumping was making Alison exhausted and she thought it would be best to just take him at face value. She was safe, that much was true. Moira was here, so was the Professor, and 'Star and the other teachers. Nazis hadn't left the island of Manhattan yet. That was good.
Alison bit her lip and turned to look at Shatterstar, at what he said next. "You can't go back out there." As much as it pained her to say. She wanted her dad safe, to be sure, but not at the expense of his own safety—that was crazy.
