Since the beginning of ep6, they've been acting like a troupe and the relationship is pretty much the same. In episode 7, Patrick's conflict arose, which led to an unofficial rivalry situation, but otherwise everything calmed down.
My main complaint with this route is how sluggish they are in reacting to the fact that MC may have a relationship on the side. We only get a couple comments and that's where their response ends. They are just waiting to see what decision he makes and this is implemented poorly in my opinion. Jill dumps MC when he ignores her at the picnic, Bella when she finds out he had fun with Cathy, Sage basically never saw him as a boyfriend,as a boyfriend, just as a dude she just fucked.
