OK, back to the comic. I wanted to address some of the comments about what people are - or think they are- seeing, and my interpretation, FWIW.
Panel one; I think that's been pretty well established. It's a mix of uncertainty on Claire's part, and a reflection of concern for what she's seeing in Marten's face - exhaustion, worry for Faye, and delight that she's come by.
Panel two - someone mentioned (probably a few pages back) that there's too much space between them. But you'll notice that Claire's hands are on Marten's chest, not around him. After seeing what's in his face, she came towards him, and putting her hands on his chest, angled her head up to give him a much needed (by both of them) kiss.
Marten's hands are on her upper arms, drawing her in for said kiss. It's not too much space, it's space that's still being diminished. Claire's hands move, her arms reaching up and encircling Marten's neck and shoulders, as we see in the third panel.
Panel three - not only have Claire's arms and hands moved (quite naturally) on Marten, but his have moved down and around her back. They have pivoted - almost a pirouette, moving out slightly into the hall.
This is where I disagree with many of the other posters. I'm pretty sure that's the front door to the apartment. The hinges and knob agree, the point of view has changed to the view from the hallway. Faye's gone to bed, they have the place to themselves, and I think he's just "welcomed" her in.
The makeouts, I'm sure, continue. And the move to the bedroom may well happen in fairly short order. But I don't think that's what was drawn.
I wanted to consult Jeph's twitter in case had commented, but I see the twitter feed's been removed from the comic site? Or am I just having trouble with it?
