I guess they'll try to fill in the gaps next week. Weird episode.
There have been a couple of episodes in the past that were so 'out there' that I had a hard time following the story line. I thought this one was going to be another one of those, but the last half hour is all started making sense and the pieces started falling into place.
In a way, it reminded me of an old M*A*S*H episode, where medic suffers such a devastating loss when he realizes that his younger brother didn't make it out of the trench and was killed, so he repressed it, and everything else, including who he is. The shrink hypnotizes the medic and BJ and Hawkeye recreate the events to cause the medic to remember.
I just can't believe that next week is the House finale already. What did they have, 8 new episodes this year?
