Continuity mistake: When Captain Archer is talking to Hoshi in her quarters, at one point he leans against the door-frame. In the next shot of him from that angle, he's no longer leaning, even though we saw him from behind and he didn't move. In the next shot, he's back to leaning against the door-frame.
