OMG - I did notice the haircut, but all I thought was, "Meh, I hate his hair short" - I didn't make the connection with the beginning of S7 at all! That's a great point!

But please don't cry! I don't think that we're going to get House+Cuddy=4evah no matter what the status of S7 turns out to be. DS and the other writers have been very firm about their position that even if the characters love each other, it's not going to work out long term.
