Grey's Anatomy Sneak Peek: Meredith Flips Out on (Naked) McHottie

Meredith’s promising rebound relationship has crashed mid-takeoff.

As first hinted in the promo for this Thursday’s Grey’s Anatomy (8/7c, ABC), Mer’s third date with dreamy-eyed doc Will Thorpe ends loudly and abruptly.

“Get out — get out,” Mer is heard screaming from her bedroom in this extended sneak peek, sending kid-sis Maggie into attack mode. Next thing we know, a frightened, confused Will is heading for the hills sans shirt and shoes.

“I was sleeping… we were sleeping… and then the screaming,” the shaken MD attempts to explain to an enraged Maggie. “For the record, I didn’t do anything.”

Watch the entire clip above and then hit the comments with an answer to this question: What do we think triggered Mer’s meltdown? An attack of some kind seems highly unlikely, so are we looking at a simple case of McDreamy-fueled PTSD? Perhaps Will was just really, really disappointing in bed? Theories below!
