'Grey's Anatomy' sneak peek: Boys on a boat

Boys will be boys… especially when they’ve got beers on a boat.

Tonight’s new episode of Grey’s Anatomy brings together the men of Grey-Sloan Memorial for a nice, relaxing day on Jackson’s (Jesse William) yacht to enjoy the sun, throw back some brews, catch some fish, and talk about… girls.

Well, girls who are their sisters, at least. In this exclusive clip, the conversation turns to the guys’ sisters. When Jackson muses it’s nice to have a sister now, DeLuca (Giacomo Gianniotti) snorts, “Trust me, it’s not.”

They compare sister horror stories — DeLuca’s sleeps with all his friends, Megan Hunt sang opera badly at the top of her lungs to annoy Owen (Kevin McKidd).

But wait, who is Jackson’s sister? When he explains that it’s Maggie Pierce (because of her biological dad, Richard Webber, marrying Jackson’s mom, Catherine), the guys object.

“Yeeeeeah, no,” says Ben (Jason George). “Maggie is not your sister.”

And since she’s not Jackson’s sister… well, that opens up some possibilities.

Grey’s Anatomy airs Thursdays at 8 p.m. on ABC.
