While JJ might just take his ball and go home, that doesn't mean his family would do the same. We HAVE seen Brad, Will, Stef, and even JP react rather strongly when people have hurt their family, and all four of them are capable of, in Headstall's words, "going apeshit" on people. But I don't think they are the major worry for either Alex or ME. I think Wade will be the real force to be reckoned with over this. For all intents he is currently JJ's guardian while they are all living in Boston, he has already set himself up on opposite sides of the fence with his mother, and I think after this one any truce with ME is going to be tossed out the window. I also think Nana is going to have some rather strong reactions to this entire thing. It affects not only her great grandbaby, but also her new boyfriend.
