Mere then drives the crew home as her VO continues, "But when the sun rises, you have to take responsibility for what you did in the dark." April is a changed woman -- as opposed to sulking she takes a giant piece of pizza from the box Alex is holding and happily munches away as she tells Alex how she used soap and water with the acetone to separate Romeo and Juliet. He just announces that he wants a beer and Mere happily points out they've got that at home, as '80s teen movie pop music peppily plays in the background and they all smile at their successful night.
Cristina's not having as much fun facing what she did in the dark, since she has to face it in the toilet bowl as Mere finishes: "And face yourself under the cold, harsh light of day." Owen is holding her hair back, still sticking with her like he promised, but after she shoves his glass of water away he does look like he's finally at a total loss of what to do about her.
And who would have thought that Derek and Meredith would be one of the most functional couples of the show? As Derek gets up for work and wishes her a good morning, she wishes him a good night, and he goes and shuts the blinds as he gazes at her. Seriously, I never in a million years would have seen that coming, but here they are, appearing to be quite happy and, dare I say, functional. Who knew?
