It can? That's the maid uniform Dani was wearing during part of the Night of the Watch, but...hold on, let me check...oh, excellent. Sorry, totally missed the calendar in the corner of panel #4 (or is that Panel #2?). Thank you for reminding me to look more closely at the background.
So, it's August, a few weeks before Adrian shows up (at the beginning of the schoolyear). So, um, what happened between here and Adrian's arrival that had Erin on the defensive? Does this comic take place just before the disappearance of her twit ex?
