Like, okay, with the awkwardness and the Britishness, fine, but it's all mixed in with a generous dollop of Hugh's own special self-centeredness.
I'm one of the more reserved English people I know and this still strikes me as massively rude. I understand not wanting to pry and the absolute horror that you might make someone cry, but a brief 'Are you ok' and then sort-of benevolently ignoring for a while them would be the usual strategy (if you don't know them well).

The only thing I dislike about this episode is that I find it very hard to believe Hugh could navigate Hotmail on someone else's computer. Unless Terri had left a blank new email open (which is possible) I'm not quite sure how he'd have managed it.

And I agree with you completely on the betrayal. I think Glenn would have been ok with Hugh backing the policy, because that's just politics and necessary. But to deliberately use a story about Glenn's son (and Glenn's face when Hugh talks about the concert and says 'it wasn't very good', when previously he has obviously told Glenn how much he enjoyed it and how amazing it all was, is just devastating).
