While House enjoys his bourbon, Cate disrobes for the examination. She keeps her socks on, saying it's freezing and there are no lymph nodes in feet. There's nothing sexy for House to see either, so he allows this and the node palpating begins. House wants to start with the nodes in Cate's breasts and butt, but she was thinking of going from top to bottom. House sighs that that could mean they'd find a biopsy-able node before getting to the good parts. While Cate palpates, House plays some Marvin Gaye and dances around. He claims it's to help her relax, and she ignores it because she knows fighting with him won't get her anywhere. Plus, I think she kind of likes it. They trade flirty barbs until House spots something medically relevant and becomes a doctor again, turning the music off and pointing out a swollen node in Cate's abdomen.

Wilson gives Cate a course on DIY biopsies. Oddly enough, Wilson doesn't need to light a fire, drink alcohol, or play sex music to do this. First, she numbs the area with some ice. God forbid she should waste the painkillers on herself, I guess. "Come on, Cate. Let's get this over with," House says, and Wilson immediately notices House's slightly more caring tone and especially his use of Cate's first name. He brings this to House's attention, who says, "just trying to move things along, Bob." Bob is not Wilson's first name. It's the actor who portrays Wilson's first name. We're very meta tonight, aren't we? I just don't know why we get to use two first names for Wilson while 13 doesn't have one. Cate inserts the syringe into her node and slowly, painfully, withdraws some fluid. A lot of fluid, actually. I didn't realize lymph nodes were full of yellow liquid. "You okay?" House asks. Wilson frowns afresh.

The two head into an elevator so Wilson can make fun of House for caring about his patient. Wilson says House has never asked anyone if they were okay before, not even when Wilson got drunk and fell down a flight of stairs. In fact, I'd wager, House probably stuck his cane out and tripped Wilson in the first place and laughed while Wilson went flying down the stairs. Wilson turns green with envy and says House has shared some kind of intimacy with Cate. Then he notices that House is following him out to lunch. House admits to it, saying he wants to see the person Wilson's meeting. Wilson knows how to escape House, however -- he turns and sprints out of PPTH, bumping into various people in his haste to outrun the crippled man.
