Poe was laughing quietly as he leaned away, letting them embrace and have their moment even as he was answering Finn. BB-8 was lingering somewhere near the door, looking entirely too pleased (as pleased as he could look, given he was a droid, but his mannerisms were in the pleasing territory) with his hasty retrieval of Rey.
He reached around and pulled his chair forward, plopping down in it so he could watch them both easily. He didn't feel like he was intruding, yet, though there was that lingering doubt that they'd want him to leave them alone but neither would be rude enough to ask. Until he felt unwanted, though, he was happy to watch their reunion. "I'm alright, pal. A lot better than you look, I'd say." Jerking his head towards Rey. "We destroyed the Oscillator while Rey and Chewie got you off of Starkiller."
