So, you remember everything that happened last week? Well, it all finishes up this week. Meredith continues to snore, and her gentle rumblings continue to cause stress in her relationship with McDreamy. She's also continuing to freak out about her father, but she eventually talks to him and learns that she got her snoring from him. He tells her about some awesome earplugs, bringing harmony back to the Mere/Derek relationship.

In more serious storylines, we learn that Addison and Mark were being testy with each other because they've reached the date on which their child would have been born had Addison not had an abortion. For him, it's all about how competitive he is and how he feels like he lost to Derek or Addison or the universe, until Callie helps him realise that he would have been a truly awful father. For Addison, it's a pretty sad week, which leads to her making out with Alex.

Speaking of dysfunctional relationships, Cristina and Burke continue to not speak to each other. But when he hears sad news about George's father, he realises there are more important things than being right, and he lets her know that he's not had any tremors for the last week. Finally, Izzie anonymously coughs up the dough for spine girl's surgery. Bailey thinks this demonstrates that Izzie is still getting too emotionally involved with her patients, and refuses to let her scrub in on the surgery. In the end, Izzie realises that she does get emotionally involved with her patients but that she's also a surgeon, and she seems determined to strike a balance between those two things.

...

In the real main storyline of the night, there's a scare about George's father because his breathing tube needs to be replaced, which is tricky considering that he just had surgery on his oesophagus. But Bailey pulls it off, and things seem to be fine. Until the random moment in which we learn that Mr. O'Malley's organs are failing and there's no way to save him. In a gut-wrenching scene, George helps his mother and brothers realise that the best thing to do is take Mr. O'Malley off life support. And it's an even more gut-wrenching scene when Mr. O'Malley dies. George is naturally devastated, and it turns out that Cristina is the one person best able to reach out to him, because her own father died when she was nine.
