In the current season, after Cuddy breaks up with House, he marries that woman so she could get her greencard. Did anything else come of this, because I haven't heard anything else about it.

They addressed it in "The Dig" when House tells 13 that his wife is currently off with her boyfriend. My guess would be that they are still "married." However, it was made clear that House was only marrying her to get under Cuddy's skin (he refused to make love to her on her wedding night) and she just needed the marriage so that she could legally be in the U.S.

I have no idea if they are gonna address it again, but they probably will there are rumors that she will be appearing in season 8.

In the season's finale, there will be مزید to come I think, because Dominica's mother will be there. Here's the link. link

Somehow I don't think we will be seeing Dominica's mother. THAT was a scenario thrown out سے طرف کی the idiotic Michael Ausiello, to explain what the actress who is the POTW could be. Seems she is a performance artist being treated سے طرف کی “Team House” and not Dominica's mother. Unless she somehow is both, BUT that would be just ridiculous.

I would imagine Dominica would occasionally be referred to in conversation, and we have been told that she will appear intermittently
