House: A Marriage Proposal and a Lover's Return?

I really hope the marriage proposal is not Foreman to Thirteen. The less I have to see Thirteen, the better. (Sorry, but I just don't like her.)

Question: How about kicking off the New Year with a House scoop? —Christopher
I’m hearing something about a marriage proposal coming in the second half of the season. Also, remember House’s loony bin lay, Lydia? There’s buzz she may get a shout-out in the upcoming episode directed by Hugh Laurie. Let’s hope Cuddy isn’t within earshot!
