Free Falling

"Even good marriages fail. One minute you're standing on solid ground. The next minute... you're not. And there's always two versions. Yours and theirs. Both versions start the same way, though. Both start with two people falling in love. Nobody gets married thinking it's gonna fail. You think yours is the one that's gonna make it. And so it always comes as a shock. The moment when you realize, it's over. One minute you're standing on solid ground. The next minute you're not. Do you have what it takes? If your marriage is in trouble, can you weather the storm? When the ground gives way and your world collapses, maybe you just need to have faith. And trust that you can survive this together. Maybe you just need to hold on tight. And no matter what don't let go."

- Meredith Grey

The fifth-year residents return for the first day of a year that will make or break their careers: Meredith faces the consequences of tampering with Derek's clinical trial and is terminated at the hospital; April tries to step up to the plate as Chief Resident in the wake of a giant sinkhole in the middle of Seattle; and Cristina and Owen are still at odds over their drastically different feelings for their unborn child. thumb|300px|right thumb|300px|right
