And specifically, I'm filling in the backstory behind this panel of Riley arriving at Buffy's party:
Riley eyed the shelves nervously. Get some wine for Buffy’s party – sounds simple, right? Well, it did before he entered the store. But facing this endless wall of brown and green glass, with labels mentioning obscure places like Bulgaria, Chile, Australia and France (okay, France wasn’t obscure) and words like ‘Brut’ and ‘Sec’; he didn’t have a clue. He was a microbrew man himself – secretly, he thought wine was a girly drink. But he’d promised.
He reached out decisively and grabbed… the biggest bottle there. Maybe if everybody got drunk really quickly they wouldn’t be able to critique his choice…
