Meredith completes her study efforts for the boards with Callie. The "Torres Method" is now inside her. As for the rest of the fifth years, they're all still scrambling as study buddies as d-day draws ever closer. They need to study real cases, but those files cannot leave the records room. That's why Alex and April convince Lexie to make use of her photographic memory by reading stacks and stacks of cases so she can quiz them. They totally overdo things until Lexie's mind becomes nothing more than mush. Time for Plan B.
Meredith invites Alex, Jackson and April over to her house, which is now their house, too. Whenever they aren't working, they'll be there studying for the boards. Then there's a knock on the door. It's Cristina. She needs to study or she's going to fail her boards. Good thing she has a house full of friends to stop that from happening. Oh, there's one more thing we should mention. Owen never asked Mark to be the Chief. He just snuck into the position. Fortunately, he wasn't all that bad.
