Desi Harperin
(Ebon Moss-Bachrach)
For whatever reason, Marnie believed that her bandmate Desi, who cheated on his girlfriend with her, would be a good person to marry. But after becoming fed up with his immature, self-indulgent behavior, they ended their romantic relationship. They’re still bandmates, though, and together headed out on tour (where he immediately slept with a fan).
