Scott Hope can't be Riley because he's all into Buster Keaton, which shows taste. Anyway he's gay, so if he did show up, it would be with some sort of thoughtful quirky gift, but then he would spend the whole time talking about how the passing "serious" cyclists look in their bike shorts, while Buffy tried hard not to fume about being passed by any other cyclists in the first place.

(I'm assuming he's come out by this point in the scenario.)
