The thing that tickles me the most in this comic is the fact that George and Zoey are drinking John and Lyn's beer. We know from the Halloween arc last year that George buys the cheap stuff
, so he wouldn't have picked this stuff up.
It's been a while since we've seen Roxy
. Initially the plan was for Zoey to go to college a year before she did, i.e.: now. But with the arc of her Grandma passing and other things happening, things got in the way for her and the comic to have her go back to school until now. So we couldn't get to this point for a while... which left her in a sort of limbo as this was always the next planned time she'd be in the comic.
Roxy is a foil for Zoey that we'll see more of now that she's in her life again. I know there's a few people that are excited to see her show back up as she was a loose plot thread that bugged them.
