Cosette accidentally flashing Marten seems very tame given her typical bad luck. She should have flashed Marten, tripped over her robe, fallen out the window, and ended up naked face up on the lawn as a busload of nuns drove by.
Nah, Cosette's bad luck isn't usually that complicated. More like she flashes Marten, and her reflexive jerk away causes her to fall over backwards and give herself a concussion while her robe flies open and she
completely flashes him...
EDIT: Ah, I found the reference to a previous scene. Follow that story a few pages.
Haha, yes, I'd forgotten how crazy jealous Steve got over that little incident. Oh, and
this one a couple of strips later is interesting. You know, if Marten could ever display that much self-confidence with a woman when he's
not just joking around, his love life might be a lot less empty. But what's really interesting is how much fun he and Cosette are both having with the whole thing -- she plays along as perfectly as if they'd planned the whole thing in advance. Hmm...
Okay, here's a wild-assed guess/speculation that is probably no more (or less) likely than many of the others so far. Perhaps Steve will fly into a jealous rage thinking Cosette deliberately flashed Marten because she's still attracted to him, and they have a huge fight and break up with each other for good. Some time after this, Cosette confesses to Marten that she does have a bit of a crush on him still, which is why she blushed when he complimented her shirt in the first place, and says she'd like to start dating him. To which Marten responds in one of two ways:
Alternative resolution #1: Marten agonizes over the decision, but finally realizes he and Cosette really do go well together, and they start dating. (Possibly leading to the end of Steve and Marten's friendship.) With this ending, we realize that the whole party-at-Tai's-friend's-place story arc wasn't so that Marten could find someone at the party to get involved with, but to get him paired up with Cosette. Sneaky, Jeph.
Alternative resolution #2: Marten agonizes over the decision, but finally decides he just can't do that to Steve and declines her offer, leaving him just as lonely and mopey as before. Whereupon we realize that the whole story arc was just a way to keep us entertained for a while without making any significant changes to Marten's circumstances.
