"Would I, now..." Ianto's eyes trail down from the canopy above them to study John beside him. Study him as thoughtfully as he can, given as much as the fyrra as there is muddling his thoughts. This is a question that deserves careful consideration, after all. Which one of them is Peter?

In the end, there's really no question at all. John really does know how to fly, never mind the fact that he needs a machine to accomplish it. But more than that, he can do magic. Ianto's seen it. And truth be told, no matter what the other man's hangups are on the matter, he thinks it's wonderful. He's wonderful. And he knows he doesn't see it in himself. That's what makes him such a good man. A good roommate. And a good friend.

"Never grow up, John," he concludes. As though the statement makes any sort of sense, out of the context of the conversation he's been having with himself.
