The sound of a helicopter ushers us into this episode, and we see a filthy and disoriented Meredith squinting and blinking into the light as she voiceovers about playing the game Memory as a kid -- the more cards you turned over, the more you got a sense of how everything fit together. I kind of think a jigsaw puzzle would have been a better metaphor since the cards in Memory are all plunked down at random, but we get the gist. And that is the structure of this episode: each of the crash victims' stories is shown individually and by the end of the episode, we can piece them all together.
She is taken to a hospital (in Boise, though I'm not sure if it's the hospital that was their original destination or not) while deliriously insisting that she has to get on a plane. The doctor tells her she was in a crash, which triggers a quick montage full of blood and yelling, and she starts to panic and demand to know to know the whereabouts of Lexie, Derek and Cristina. As the doc tries unsuccessfully to calm her, Richard and Bailey push past a protesting staff member in the hall and walk in; Bailey is carrying Zola and the sight of her daughter seems to calm Meredith. She holds her arms out and Bailey hands Zola over; Mere holds her tight while repeating, "Mommy's here," Bailey looks on, worried and Richard just looks devastated.
Sometime later she shuffles into Cristina's room, wheeling her IV bag along with her, and lays down on the bed next to her friend. Cristina just stares at the ceiling as Mere tells her that they are taking a plane back to Seattle the next day and have no choice in the matter because Mark and Arizona are in such bad shape. Given that, she ordered Bailey to sedate them all so that they will have no memory of having to fly again. Cristina doesn't respond even when Mere reportedly asks if this was right, and finally Mere grabs her chin and pulls it around so they are face to face. But Cristina's eyes are unfocused and she's not seeing her friend despite Mere repeatedly calling her name.
As promised, the five patients are all dead asleep and strapped to their gurneys while a sixth gurney carried a body bag. The plane is rocking and rolling and Richard and Bailey are terrified, clutching on to straps at their seats. Bailey admits that all she can think is that they are going to crash on an island and be attached by a polar bear, which deeply confuses Richard. She grumbles at him that he should watch more TV.
