Rufus sobs again when Robert speaks. Sobs because he's a cheeky bastard and yes, he was right, and he, Sixsmith, never believed it would be like this. He didn't imagine it would be so like this when they found each other again. He's struggling to draw in the breath he needs to reply, barely able to keep himself standing, even, especially when he feels the tender press of lips against his cheeks to kiss away his tears.
"Is this our brave new world, then, Robert? This is our better place?" Do I get to keep you, here? he doesn't ask, it goes unspoken, but he doesn't want to hear the answer, either. He doesn't want to have him ripped from his arms once more, doesn't want to live another forty years alone, doesn't want to have to die again and again for more precious moments with the man he will love to death in every life.
Rufus nods his head in agreement to them going to bed. And then laughs because Kaya wasn't joking, either. He is going with his new roommates. Presumably the man that accompanied Robert has been looking after him-
"Bed," he says, because he's suddenly equally as exhausted but now aching with the need to feel Robert's body pressed to his own through nothing but a thin layer of fabric, if that. The feeling he has woken up craving too many mornings to count. He wants that now and he's still almost too afraid to accept that this isn't a tormented dream of a murdered old man. But he doesn't care if it is. It feels so real. It's enough.
Sherlock thinks he should probably have been expecting the tackle, though it's very careless to foist upon someone on slippery ground and he does stagger slightly, despite Kaya being so slight.
"Are you referring to me?" he asks, not sure if he should be offended, but Kaya is gripping him so tightly and all but humming with happiness that he supposes it to be a term of endearment. "I'd best take these two home, I suppose. Would you like a cup of tea? Perhaps some loud background noise-" because no matter how tired the two men look he's almost certain they're going to want some intimacy from each other.
His arm still around Kaya, Sherlock sets off again, following his own footprints back in the snow. Robert will follow, there's no doubt about that.
