We jump back to the days of the plane crash. A rescue team transports our favorite docs from the woods. Meredith freaks out in a hospital. She's looking for Derek. She's looking for Lexie. Mer calms considerably when Richard and Bailey show up with Zola in hand. Later, she visits Cristina, who seems to be in a catatonic state. All of the injured docs are sedated as they are transported home on another bumpy plane ride.
Time passes. Derek and Meredith argue about moving to Boston. She can't even think about that right now. He's wondering if they'll still want a surgeon with a hand that's only at 80%. At work, Meredith tries to keep her colleagues positive. She insists that Mark will come out of his coma and Arizona won't lose her leg. She states this emphatically as Jackson checks up on a still-catatonic Cristina, who is kept in bed with restraints. Meredith begs her to say something. It doesn't happen.
We flashback to rescue day. Derek tries to tell the doctors treating him that he's a surgeon as they try to salvage his hand. Callie does follow-up work but the nerve damage that was done is what gives him that 80% number. Derek may never operate again. That doesn't stop him from trying to talk another surgeon through a tricky procedure using his approach. It doesn't go well. Mark gives his pal a pep talk reminding him that he loves a hopeless case. That's why Derek talks Callie into performing a risky nerve graft surgery that could get him to 100%.
