Sulu nodded at that as though it was obvious, but he felt a little silly and guilty anyway for being unable to stop himself from thinking that way. That Jack had seniority, so to speak - but really, how could he not? It wasn't as though he was upset by it, or anything. Ianto just had known Jack for long, had been with Jack for longer; it was only fair for him to assume that there was more depth there than he could tread at the moment.

Still, he resolved to try not to think about it like that from now on, if he could help it. So instead he just smiled and said, "Yeah. I don't think he'd know what to do with himself if he had to rank us. And that we're all pretty lucky to be on good terms with each other. That makes things a lot easier, obviously." Especially now, after everything that had happened.
