Panel 1: Okay, it appears from the sunburst around Liz's fist that she is knocking with anger. And another double entendre with the answer "Coming!"
Panel 2: Liz looks angry and Susan looks...apprehensive? Hard to tell, since we haven't seen her much. Liz does seem to be keeping it civil, although of course we can't hear her tone. And I like the imagery of her breath cloud.
Panel 3: Another breath cloud. Shouldn't we be seeing Paul's face, so we can gauge him? At least he's not stuttering. And was not afraid to come to the door, as Eric was. Liz's eyes are narrowed and she's going for the kill.
Panel 4: Well, that's ambiguous, if anything ever was. Paul's open mouth could mean he's busted, or it could mean he doesn't know what she's getting at. Susan is looking at him, but again, I'm not sure why. Anyway, yes, it's too late! It was too late when you didn't call; it was too late when you half-assed your agenda for the visit; it was too late when you left Mtig and said it was "for good"!
We waited an hour for this?!
