What would you do?

I think you have to speak up at halftime and tell this guy to call in his area. You may piss him off but better he be pissed off than continue to put up with such crap. BTW, it's likely that he's the one looking like the fool.

You may need to make a decision as to whether you want to continue working with the smaller group. If it continues to create these types of situations, I would probably drop it.
