Mere's wheeling Natalie through a corridor when Natalie asks her to stop. She wants to walk, she says, and feel her body move while she can. Mere comments that Natalie seems incredibly okay with her prognosis. Natalie says she's more than okay; she's a little in love with her prognosis. "It woke me up. It woke my marriage up. I've been sleepwalking about fifteen years, and now I am wide awake." She says she's having this MRI for Kyle, because he's not ready to let go, but she and her aneurysm? They're good friends. Unforgettable! That's what they are!

Addison finds McDreamy in a lab and says she's been looking for him. McDreamy is involved with looking at Natalie's aneurysm film. Addison: "You know who Catherine Deneuve is?" McDreamy says yes, he knows -- she's a hot French actress. Addie is all proud that her patient's husband said she looked like her. McDreamy totally, totally rains on her parade: "Isn't she blonde?" Addison's all, uh, yeah, okay, you're busy, bye! Ugh.

Izzie and Denny, sittin' in a tree. Actually, just playing Scrabble. Izzie gets 25 points with the word "screw." She restrains herself from adding, "What I would like to do to this magical heart patient." Denny says that's not fair; she didn't tell him they were playing naughty-word Scrabble. Izzie says that's just his dirty mind. Denny says sometimes it's just hard to tell where she's coming from. And then they have a big talk about how Alex said they were together. Izzie, of course, denies it. Denny thinks this is sweet, and thanks her for clearing that up. And then, according to my closed captioning, Denny [breathes raspily] and [gasps], so Izzie has to put an oxygen mask on him and page Burke. Draaaaama! Commercials.

When we return, Burke tells Denny that the news is not good: he wants to install a left ventricular device to help his heart pump. Denny quips, "You guys are trying to turn me into a robot; it's all part of your evil plan." Chuckles abound. Izzie tells Denny that it's a bridge -- not to the great beyond, but something to keep him alive while they wait for a new heart. The catch is, Denny has to stay in the hospital until he gets a donor heart. Denny doesn't like this plan. He asks if there are any other options, and is met with silence. And then, because he's not getting enough blood to his brain, says he needs a little time...to think about it. "Don't take too long, Denny," Burke says, and turns away dramatically.
