" He’s becoming useless. Worse than useless,” Sam said. Then, relenting, he said, “We’ll get past it.”
“You mean you and Quinn?”
“Yeah.”
Astrid considered just keeping her mouth shut, not pushing it. But this was a talk she needed to have with Sam sooner or later. “I don’t think he’s going to get over it.”
“You don’t know him that well.”
“He’s jealous of you.”
“Well, of course I am so terribly handsome,” Sam said, straining to make a joke of it.
“He’s one kind of person, you’re another. When life is going along normally, you’re sort of the same. But when life turns strange and scary, when there’s a crisis, suddenly you’re completely different people. It’s not Quinn’s fault, really, but he’s not brave. He’s not strong. You are. "
