When you freeze frame it, there's this bit when Blair bats away Jim's hand as they're going down the corridor to peek in the stairwell, almost as if it's too much concern. But they seriously don't lose contact for AGES.

And I know, but I can't blame them too much. It's like Gustavo and the blowtorch; does he threaten to use it on Jim? No. He threatens to use it on Blair -- but carries on asking JIM the questions. And he's only just met them!
