Well, so far I think they aren't so much "moving" to PC as being there because Starr had an accident outside town and is in the hospital. Starr et al. weren't heading to PC, but somewhere else (Boston?? I forget) and just passing by PC. Now her parents are there because she's been hurt, just like any normal parents would be. I've missed a couple of shows, but so far haven't seen John. Maybe he will be pursueing them, a la Les Miz.
I agree, Starr and Michael---good pair---she's already putting him through a lot of anguish, and he can identify with her pain. at the moms comparing worst dads!
I also LOVE seeing all the old time actors return--back from when Robin was a child and I was just starting to watch GH. Heather was before my time, but I do know who she was on the canvas.
