An awful lot happened last week between Hannah (Yvonne Strahovski) and Dexter (Michael C. Hall). Girl drugged boy, girl didn’t kill boy, boy found girl, boy didn’t kill girl, boy went to kill girl’s new husband, only to find she beat him to it. So what are the duo up to, or no up to, this week? Tough to say, because Dexter’s already got a young mentor who’s lowering the population at Dexter’s apartment complex – and that can’t be good.
