Billy looked at Bart with a sly grin. "Uh... I'm practically Willow here... The lesbian from Buffy, not the midget with Val Kilmer." He laughed and shook his head. "And I have some sort of parent trap twin thing going on too. And my boyfriend turns into a mini green rage monster. Basically... what I'm saying is, you probably can't shock me at this point."
Which was true. Unlike their first meeting, where Bart had whisked Billy away to St. Louis unexpectedly, Billy had grown significantly in the weeks since. At least in terms of accepting that his life was full of weird.
