I'm liking Martha more. House hiding his ideas from was entertaining, but the fact that she's basically a genius is awesome, especially since her moral compass points directly opposite to House's. She makes a great foil and comes up with just as implausible, though correct diagnoses. Her need to tell the patients EVERYTHING is going to cause her problems though. Sometimes, it's better they don't know all the gory details - some patients like to be blissfully ignorant. I'm not one of them, but I know many who are.
Wilson & Sam with the little girl was a sweet side story, and showed another side of her. I don't know that she's ready for parenthood (Wilson is - he's been a surrogate father to House for years lol), but if she IS going to have a kid, she'd better get on it soon. I can see the expiry date on her eggs from here. lol
