Back at the hospital, Cameron is trying to explain to Mrs. Bob that every bathroom in the hospital is broken, and Mrs. Bob calls her bluff by piledriving past her and going anyway. House runs up to the women's bathroom containing her, waiting for her to emerge from her stall. When she finally does, she's slightly incredulous to find the whole team waiting for her. At least Cameron is logging some equal-opportunity bathroom time, finally. House takes Mrs. Bob's hand, which she tells him (and us) is wet. Here's why: "The damage to your husband's lungs is permanent. Kidney damage is reversible, and with the right therapy he should regain neurological function. So other than the fact that he's not going to running any marathons, he should be fine." Mrs. Bob tries to celebrate what she perceives as good news. But wait! There's more: "I didn't have a problem with you going to the bathroom. I just didn't want you to wash your hands." One quick, cautionary tale about Egypt later, House tells Mrs. Bob that ancient Egyptians learned that mixing something called stanischloride with gold turns a surface bright purple. With which he pulls his hand away, and we note that Mrs. Bob's hands are bright purple. So unless she's actually made of gold, she's been poisoning her husband with vast, vast riches, an arthritis remedy extremely popular in Mexico. (And monkey's brains, though popular in Cantonese cuisine, are not often to be found in Washington, D.C.) She's busted. She tries to tell House that he's wrong, but...

...he's not. This is why we cut to Mrs. Bob being led out of the hospital by the authorities, Team House arguing the myriad reasons she could have done it. No one will ever know. The episode is too close to over. Cameron comes to offer her cash to House.

And, back at House of House, the good doctor opens his refrigerator, removes a Post-It Note reading "Property of James Wilson. Trespassers will be prosecuted!" from something that looks delicious, and clicks on his home answering machine. One message tells House that Wilson's apartment could be lost to a better offer, but that if Wilson calls back ASAP, he could get the place back. House, his heart growing a size bigger every minute, deletes the message to keep his best friend around. Awwwww! Seems like a call that time-sensitive probably should have come through on the man's cell phone anyway.
