Squall's not in his dorm room right now. Maybe you can get some insight into him by looking around?

There's a lot of carefully written, thoughtful analysis of Squall's character out there. I don't know if I'm capable of anything more articulate than pointing at him and going 'look at him, he's perfect, I love him ♥', but I'll try.

Let's talk about Squall's inner monologue.

Huh, there's only one bed here. Which makes sense, as it's Squall's room, but sometimes Squall rests in this room with his teammates, right? Isn't that awkward?

This bed is not the place where Squall dreamt he was a moron, but let's talk about that as well.

There are some bad drawings of Squall and his friends up on the wall. It doesn't seem like the sort of decoration Squall would personally choose. Maybe Selphie crept in here and put them up?
