Q is on his feet when he sees the tears spilling down Robert's cheeks. He flicks his cigarette away and takes the six steps towards him, nodding his head gently. Yes. They are. Each other. Past and future. Or present and past. Present and future. It doesn't matter.
He pauses only a fraction of a second when he gets to the point where he can see over the edge of the roof, but the usually twisting in his stomach seems to have taken a backseat to the need to comfort Robert.
Q huffs out a little laugh of incredulity as he cups Robert's cheeks, wiping away the tears with his thumbs and then sliding his fingers up into hair that feels just the same as his own. It's fascinating, it really is. And he can't stop himself from touching.
He leans in then, pressing his lips to Robert's forehead. And he doesn't pull back. His hands move to Robert's shoulders and he pulls him in gently, resting his chin on the top of the other man's head.
"It really is a pleasure," Q repeats softly. Because he doesn't want Robert to think that he even so much as dislikes the man he once literally was, or judges his choices. No, it's an absolute pleasure to be able to do this right now.
