At some point Foggy gets turned into a vampire. Matt freaks out but Foggy takes it fairly good humor. They change the hours their practice is open (see, Matt? I told you 24 hours attorneys meant more clients) and buy a lot sunlight blocking curtains. Matt hides all his crosses and erradicates any pencil or stake-like thing.

But the really bad thing? Matt can't hear Foggy's heartbeat anymore.
