So Ben likes a woman in roller skates. Everyone has a thing, right? For Ben Wyatt, it’s roller skates, political activism, and the music of the early nineties. If he’s not on your laminated list of fictional men, I’m judging you. Ben’s a nerd in the same way real people are nerds: he gets passionately obsessed about things. Leslie gets passionately obsessed about people, which is why they fit together so well. She pays attention to everything Ben loves and gives it back to him in the form of a theme party. He returns the favor by missing that entire party to watch Leslie stage a filibuster for the town she represents.
