I don't like the odd way this episode is being edited. (Mostly the quick-cuts to commercial) It worked for last season's finale and some other episodes but it doesn't fit the tone of this episode.
Hard cuts to commercial seem to have become pretty standard in TV these days. The old "fade in/fade out" doesn't seem to happen much anymore.
It is refreshing that they finally redid the titles and promoted Jacobsen and Wilde to full regulars. It's particularly reassuring to see Wilde's name there, given the leave she's about to take.
Nice to see a departure from the formula. There's still a medical puzzle to solve, but it's not a patient-of-the-week with an intractably exotic and life-threatening problem, it's a fellow doctor and it's a less extreme crisis played for laughs. The main problem being analyzed is the new House-Cuddy relationship.
And yeah, they did show us a remarkable amount of Cuddy skin here. None of the usual TV stuff where the woman in a post-coital scene inexplicably has a bra or camisole on, or has the covers hiked up two feet higher than the guy does. It was, err, refreshing.
