Aside from when the excerpts tie into the AU guessing game, we don’t announce which AU they’re from! It’s obvious with a few– Dean’s only small in BC and BL, and clearly if Sherlock or John’s around, it must be BC, and with the rest, you’ll have to figure it out when the poll comes up!
This way, we keep the poll as randomized as possible to avoid one AU dominating, and still have some fun.
