The way the previews for Grey’s Anatomy Season 8, Episode 6: “Poker Face” made it sound, we thought this episode would be all about sex. And it wasn't. Only, say, two-thirds of it was about sex. Nah, we kid, there was a lot more actual medicine in this episode. Here are all the deets.

Mark (Eric Dane) has shunted all of his cases to Jackson (Jesse Williams), so he has free time on his hands... perhaps a little too much free time. He starts cooking with Arizona (Jessica Capshaw) to keep his mind sharp (or so he says), and the two of them prepare dishes that look and sound scrumptious: eggs benedict, maple-ginger scones, braised short rib, etc. The only problem is that Mark's culinary curiosity is coming at the expense of Callie (Sara Ramirez) and Arizona's sex life. So finally, Callie comes home with beer and pizza, dumps Mark's coq au vin in the trash, and tells him to beat it. Then the ladies get to work making a "calzone." (See what we did there?)

April (Sarah Drew) is helping Bailey (Chanda Wilson) with the islet trial but soon becomes overworked, so she secretly recruits Meredith's (Ellen Pompeo) help. Meredith, in turn, turns to Richard (James Pickens Jr.), and the two of them make a breakthrough. Bailey is mad as hell when she finds out that Meredith has been helping but grudgingly takes and implements Mer's research. Finally, Richard forces Bailey to go home and sleep before picking up the trial's baton himself.

Meredith, now on the OB/GYN rotation, receives a patient named Mary who has an apparently-inoperable butterfly tumor in her brain and only months to live. But, knowing her husband doesn't know the meaning of the word "inoperable," Meredith has Lexie (Chyler Leigh) take the case to Derek (Patrick Dempsey). Meredith also convinces Mary's husband Clay to risk the few months Mary would have with her newborn child for the possibility of a lifetime together. Derek totally comes out of the surgery looking all dejected, but that's just a ruse: he actually rocked the surgery and Mary is fine and tumor-free.

Owen (Kevin McKidd) informs the residents that he's keeping track of the bad outcomes each of the fifth-years has in the OR. Alex (Justin Chambers) already has five, so he's reluctant when his elderly ladies-man patient Chuck wants a riskier operation because it would leave a smaller scar. (Considering Chuck is played by Lee Majors, can we say that Chuck wants to leave the OR looking like "six million dollars"?) After Alex balks, Teddy (Kim Raver) decides to grant Chuck's wishes and chides Alex for being too cautious for the sake of his reputation.

Cristina (Sandra Oh) is on an OR rotation, which teams her up with Callie. Their patient is Tyler, a young man with cervical spondylosis, a condition which makes him double over. In the midst of the surgery, a faulty wire makes the monitors spaz out. Cristina freaks and takes herself off the case before realizing that it was just a technical difficulty. But it's too late: Callie won't let Cristina back on the case, and she criticizes her for being too cautious for the sake of her reputation. (Sensing a theme here?) Callie eventually fixes Tyler's spine, and he grows a spine, so to speak, by telling his ever-bickering parents to get a divorce.

In other news, Cristina and Owen try having sex all around the hospital but keep getting interrupted by Richard, Derek wishes Lexie could assist him in the OR like Meredith could, and Alex is seriously mean to April... even though we can't totally blame him since April is a bit shrill. All in a day's work at Seattle Grace-Mercy West...
