Sean ends up on Maggie's front porch, presumably because he knows she is a nurse and hopes she will be able to help him without him having to go to a hospital (and thus having to call the police). She doesn't want to do so, because she recognizes that he's lost a lot of blood, but she agrees to help for now.
Peter and Sunny did indeed end up in bed together, and while they're lying there, Sunny confides in Peter that she lied about the ticket. She tries to make it all okay because she held all those lottery parties and always made sure that everyone put in their dollar, and the one time she didn't do it, no one came to see if she wanted to put in her dollar. Peter throws out another one-liner, saying that if she wants trust, she shouldn't try to gain it by lying. Sunny does take all of her money not invested in the company and gives it to charity, to try and impress Peter. No telling if it works or not.
Damien and Galina visit a doctor to find out that Galina has some history of birth defects, and Damien appears to be having second thoughts about the paternity test - or perhaps he is just being sucked back into Galina's web. Frankie, meanwhile, is caught by her mom and the credit card is shut off again, but she gets by when she meets the son of the hotel owner, who comps her room, at least for the night.
Cameron and Beth make a bit of peace and Cameron meets his half-sister, and in so doing he finds out that she wants to go around the world. So one night he and Beth visit her and give her what she wants. What I find odd here is that the present apparently cost three hundred thousand dollars. I have no problem with doing things in style, but good grief that's a lot of money.
Nina and Peter break the news to their girls that they are breaking up, and Violet (the oldest) runs away to the carnival, wondering why they can't be happy like the time when daddy brought the carnival to the back yard. In the end, Peter asks Nina to stay the night, saying he'll sleep on the couch. So perhaps they will reconcile and everything will work out.
At the end of the episode, Sean collapses and Maggie takes him to the hospital (well, an ambulance does), and while he has an operation to save his life, he also is confronted by the police who say that Tally tells them everything - about how Tally says he killed Zoe and threatened her. The last thing we see is Sean getting handcuffed to the bed. Once again, no previews, so no idea how this will work out.
