Sheppard frowned as McKay came into the cafeteria, caught sight of him and Ronon sitting together, and turned and walked out without getting any food. Something had been wrong ever since they returned from the planet with the ascension sanctuary, but he couldn't get a handle on it. He wished Teyla was here but she had left for the mainland to spend some time with her people and McKay wasn't talking. Or rather, he was talking, but it was all complicated explanations of how a time dilation field worked. Sheppard understood how six months had passed for him while only a few hours went by for his team and he didn't need any more information about it. He was just happy to be home, and the team was happy to have him back. So why the tension between Ronon and McKay?
The colonel sighed. There was no point in asking McKay again. He would just rattle off another long speech about quantum mechanics and rush off to his lab. Maybe Ronon would be more forthcoming. "Want to spar?"
"Sure."
