EW Spoilers 

Im hoping it mean, sleeping together or passionate act and hoping its Chase and Thirteen <3

I think the fight is gonna be 13 and Chase *chuckles*.
But it would be pure gold if it was Wilson and Cuddy.

I would like to see a Chase/13 cat fight *see what I did there XD*

And it's obviously House/Cuddy... she'll find him.
Can't they just have some... I don't know, decent time together? Instead of all this crap?

I think...based on other spoilers, that the brawl is 13 and Chase. But this just says that they will 'be involved in a brawl'---so that doesn't necessarily mean that they brawl with each other right? Maybe they find themselves in an unlucky situation and end up having to fight someone else together?

the person at gunpoint is obviously either thirteen, her friend, or chase

OK I was wrong. Just saw a promo pic that makes it clear that the two ppl are brawling with each other!!! haha. Probably my favourite promo pic ever! Sooo random!

The person at gunpoint could be Taub...shotgun wedding anyone??? :p
