[There's something in the way Keith asks that, the phrasing of it, that roughness he hears. He looks up at him, feeling shaky just seeing Keith's reaction, his face, the sound of his voice. He doesn't have any bearing in this conversation, no point of reference, for why the atmosphere should be like this, should feel like this, all the while they're both looking at each other like this. He feels terrified in how exposed he feels, how completely rattled he is just from these last few moments.]
[He's quiet for a long moment, just looking at Keith, trying to assess the conversation as he thinks back on it. The same thought keeps pushing through-- Keith always tells him he's glad that he's here to listen. That Shiro can talk to him, too. If it's a matter of things difficult to admit, he knows it's not that. He doesn't let himself hope but he... tries to breathe, to calm down.]
Keith... I'm sorry. I'm always so stuck in my head.
[He sees Keith's hands shaking and, for a moment, he hesitates-- but five minutes ago he'd have done this, so he's doing it now and hoping Keith doesn't withdraw: he reaches up and covers his shaking his hands with his, touch gentle.]
