Later that night, Liza's in her third, more formal work outfit cleaning up all alone, when a voice whispers her name. Cliff shows up behind her in the satanic mask that Eddie had been wearing, and proceeds to explain to her quietly how he killed Eddie. But, just kidding! He clarifies that is how he would kill Eddie if he'd done it. Until this year I had no idea this "If I did it," was so trendy. He then tells her to mind her own business, and trots out to the car to drive Nikki and Spats home. His phone rings and he tells his mom that he'll be right there.
Greta gets home and Skip is waiting up to tell her he's decided to stay in town. She argues that she doesn't need him but he tells her there was one night otherwise. Which night do you think that might have been? That's right, the night Eddie died, when she came home freaked out and he made it "all go away." He claims he pulled strings and made sure the cops didn't ask any questions. Greta can't believe he would think she killed Eddie, but he just says he doesn't ask that question in his line of work.
And Johnny goes to visit Liza in her Garage Lab of No Good, who admits she snuck into Cliff's house and found something. He tries to act all high and mighty but finally Liza pulls back a sheet to show Greta's angel costume artfully arranged on a table, like you do, and covered in bloodstains.
The final montage shows Bob finding a peace offering from Johnny in the form of a putter, and everyone else looks at pictures or at mirrors or into thin air looking antsy. Everyone but Nikki, that is; she looks blissed out while she pets Spats because of her new great boyfriend Cliff. It's a shame that Cliff has dropped her off in order to go do the dirty with none other than...Eddie's mom.
Bum bum BUUUUUUUUM.
