Night falls on the hospital. Champagne corks are popped in House's office, where all the guys toast to Cuddy's genius (and even House has to admit that that's what it was) in saving their jobs. Cuddy stops by, and is warmly greeted and given a big flute of champagne. She proposes a toast to herself, "great champion," who saved everyone's jobs. And if it's poor form to toast to yourself, it's even worse to down the entire contents of your glass afterwards. Everyone starts to realize that Cuddy isn't in a partying mood. She puts the empty glass down and says that if House had the ability to get along with people, the hospital would still have its hundred million dollars, which could have saved lives and helped a lot of people. Keeping House may have been "the lesser of two evils," but that doesn't mean they should be happy about it. Much like how I doubt Sean is passing out cigars over in the neonatal ICU to celebrate his decision to choose the lesser of two evils. Having ruined everyone's good time, Cuddy leaves to mourn, and suggests that everyone else do the same.
And they will, in a montage. Sean holds his baby. Foreman watches him from outside the room, because they couldn't think of anything else for Foreman to do. The Vegans take care of their baby and its crappy thymus gland. Wilson unpacks his office. Chase walks by House's office as he leaves for the night. House is still at work, checking out what I'm guessing are Olive's CT scans. The episode ends there, as fortunately for us, the director chose not to show Cameron standing outside House's office window in the rain.
