MMXXII

It was a gin and tonic... later, when I was browsing the list of drinks in Revan's post, I realized that almost no one would guess what that drink was, and I even thought about asking Revan to specify what it was, but I decided against it...
In principle, yes, many things add up. For example, Kosha mentioned that she likes green tea, and Locken liked to talk about coffee; we could have tried harder to guess more. But I decided in advance that I wouldn't overthink it and would just go with the first thing that came to mind, and it turned out to be pretty good.
