"Claudius?!" Magnus says, surprised, before he remembers some of Galahad's stories about Claudius and -- well, Grantaire, actually, but Magnus supposes where there's smoke, there's fire, or whatever. He course-corrects: "He's always super straightforward with me but I guess I'm no trying to be in a relationship with him. I think with some people though it can be hard to be emotionally vulnerable." Like Alex. Alex finds it hard to be emotionally vulnerable. So does Magnus, sometimes, but he's working on getting better at it.
