"Grey's Anatomy" Recap: 5.3 "Here Comes the Flood"

Water, water everywhere — Later, George is sitting down to take re-take his intern test. A drop of water hits his exam booklet. He looks up and sees a soggy ceiling tile bowing ominously down at him.

Down the hall, the aneurysm guy slips on some more water and cracks his skull on the floor.

The Chief tells his maintenance man to fix the leak without shutting off the water, because suddenly, he's not just a motivational speaker, he's a plumber. The maintenance guy agrees to the Worst. Repair. Plan. Ever. and wanders away to take his mandatory union break.  We never see him again.

Found out — Erica finds Callie at the nurse's station but doesn't look overjoyed to see her virginal girlfriend.

Erica: We have a problem. Mark Sloan has found us out.
Callie: [laughs] Mark's known from the beginning. I told him.
Erica: He's Mark Sloan!
Callie: What, you don't have a person that you talk to about things?
Erica: You are the person that I talk to about things…

Callie seems to like that notion a little bit.

Erica: …and I like to keep my private life private from everyone. But most definitely from Mark Sloan.

Izzie happens by and Erica lowers her voice like they're talking about their salaries. Erica gives Izzie a sideways glance and scurries away, to go back into her closet. Izzie isn't paying any attention to the lesbian drama going on three feet away because she's eyeing an "Apartment For Rent" notice on the bulletin board.

How are those new rules working out? — Cancer patient Shelly is sick, but even sicker of her sister, Jenn, who can't stop talking about her condition. Shelly begs Meredith to tell her a story without the word "tumor" in the title.

Meredith tells her the one about the princess with two roommates, a prince and one tiny castle. Shelly likes the roommate who bakes and the other one who fixes things, but she like the prince with the fancy hair best of all. Read it again. Read it again, Mommy!

Meanwhile, Derek offers Cristina the chance to bore holes in headache guy's skull if only she joins his Facebook cause, "Izzie and Alex Must Die." Since she's always been a sucker for a bone drill, she accepts his invitation.

In the background, Little Lexie is observing the patient and suddenly has an epiphany. But the grown-ups, Derek and Cristina, are talking, so she hop-scotches off to find Sloan and tell him about an article she read when she was just an earnest pre-med student. She remembers every word of the article.

Lexie has a photographic memory. Big deal. If you obsessively replay each moment, word and gesture of your chance encounter with a hot Starbucks barista, you, too, can recall every detail, five years later. That's not called photographic memory. That's called being a lesbian.

Anywhoosh. Lexie asks Sloan to take a look at Jack's nose because he might not need a lobotomy. He might just need a really big tissue. Sloan is actually an ear, nose and throat specialist, when he's not performing boob jobs and face lifts. When his patients cough, their breasts expand. It's the weirdest thing.

Upstairs, Izzie invites Alex to share the awesome apartment she found on the bulletin board but he'd rather live under an overpass than with her. Crest-fallen and feeling "person"-less, she retreats to fantasize about the only person who really loves her, Denny. Too bad he's deader than disco.
