While Cameron and Foreman run off to do that, Chase goes to see House in his office. His attempt to apologize or at least explain his outburst is cut off by House firing him. For real. Shocked like the rest of us, Chase stammers out the question why. House says that Chase has been there the longest and has either learned everything he can from House or learned nothing. "Either way, it's time for a change," he concludes. Chase doesn't know what to do except stop himself from crying as he utters a "Fine." He leaves the office. Well, I wasn't expecting that to happen.
Cameron and Foreman are finding nothing on the PET scan when Chase walks in with all his stuff packed up, including an umbrella and, oddly, a ping-pong paddle. He tells them that he's just been fired, so he'll be going now. Cameron doesn't think this makes any sense, but Foreman thinks House is taking out his anger at Foreman on Chase. Cameron remarks that Foreman is making this all about him, which would be a good point if it wasn't coming from the woman who usually makes everything all about her. While they bicker, Chase does the job he no longer has and sees a hotspot on Marina's humerus. That's humerus, not "humorous." There's nothing funny about arm bone cancer, people. When Cameron turns back around to talk to Chase, he's gone without even an "It's Tuesday; I like you."
House celebrates his loss with a bad case of guitar face while he air-guitars on his flame cane, dancing around a lot more than his bad leg should allow. Hey, you know what isn't sexy? A man in his later forties pretending to play guitar on a cane with flames on it while making all manner of weird faces. I'm just saying. Fortunately, the session is quickly interrupted when Cameron and Foreman march into the office with shared angry expressions on their faces. They hold the PET scan results hostage, demanding that House tell them why he fired Chase. That's great news for Marina, whose treatment is now being delayed by office personal bullshit. Treatment that she wouldn't have gotten at all if the guy who just got fired didn't see the hotspot on her PET scan, by the way. Foreman asks whether House fired Chase to make him stay, which makes Cameron think that Foreman told House to fire Chase. Foreman immediately says no to this while House says yes, flashing Foreman a "ha ha, now she'll hate you and give you attitude and stuff" smile of victorious work-relationship sabotage.
