Martha runs over to the isolation tank and tells House to examine stepdad's body. House says no way, as he's given up and decided it's smallpox after all and hopes that if he just stays as far away from the body as possible, he won't get it. But when Martha tells him her theory and about the captain's dead bald cat, he's suddenly hopeful again. Broda yells at him to step away from the body. He does not, but says it's a little tough to look for eschars while wearing big stiff protective suit gloves. And with the audience of the stepdad's family like right there, I'll bet. Martha tells House to take the gloves off. If he truly believes it's rickettsial pox, he won't need them anyway. Sure, but let's not forget that House is stuck in this room in the first place because he truly believed the stepdad had kidney cancer. House rips off the gloves and searches the stepdad's body desperately just as the CDC guys come in. Before they can ruin everything, House finds the eschar. It turns out that all Broda needed was some real actual evidence, and now that he has it, he has no problem admitting he was wrong and ordering that Julie be started on antibiotics.
Smallpox crisis over, the useless PPTH security guards unlock the lobby doors. Cancer kid's mother is the first person to run inside, and she finds Wilson and Sam with her daughter, who is apparently done with the treatment. She jumps out of the wheelchair to embrace her mother and the real Lamby. Wilson says Sam did a good job with her, but Sam says she kind of sucked for a while there. "It takes practice," Wilson says, suggesting that they both practice on a kid of their own. Yeah, because it's a really good idea to have a kid with the woman you've been with for a couple months and who your first marriage to ended in divorce.
Julie's feeling better and her mother and stepbrother are allowed in the same room with her. Mom is thrilled, of course, but stepbrother is kind of upset since his stepsister kind of killed his dad and stuff. You understand.
And House is out of his protective suit and in Cuddy's office offering to buy her breakfast. When she declines, he graciously offers to let her pay for their breakfast. But she's still pissed off, saying that she was only nice to House before because she thought was going to die. Now that he isn't, she's still nursing that grudge. Oh, good. Now we can look forward to them extending this little squabble into a third episode.
