"Sounds good. I'll be here." He's not going to make a run for it while Steve's out. The thought is tempting. Now that it's all catching up to him now. But he won't. He'll be a good little host about it. Try to set up the couch in a way that should be comfy enough. Shove things away. Pack a few things. Hell, a quick shower while Steve's gone isn't a bad idea anyway.
