So Wirt tends to just go and not worry about whether someone's there or not, but he can't seem to get the words out.

"B-But I-- I can come back later, if you'd rather be alone?" He forces an uncomfortable laugh. "I mean, it's not like I'm in any hurry, since we're all stuck here."

If it helps, it might not be possible to be more awkward than he is.
