Maggie looks cute
There are a few publicity stills of KLS wearing that outfit, so apparently the show thought she looked good in it too.
6:15 AM, Maggie is dressed rather early - I guess a left-over habit from opening the diner.
I've always presumed she's still dressed from the day before. Doesn't she make a comment that she'd been looking for Joe most of the night? And, well, just because she's wearing a different outfit from when Joe left the cottage to go to Stokes' place doesn't mean anything in the DS universe where people wear different clothes in a different iteration of the same scene.
Though I suppose it's also possible that she looked for Joe, obviously didn't find him, went home and to bed, but couldn't sleep, so she got up really early and got dressed.
Why does Joe have fake side burns, really
Does he? I can't say I've ever noticed. But I'll pay attention from now on.
