I'd be surprised if slut Holly wouldn't be into whatever Ian wants at this point too.
Yes, perhaps slutty Holly could be convinced of a Jeremy threesome if Ian suggests it, maybe it will happen on its own as Ivy sinks her claws deeper. Unfortunately Jeremy kind of has to be the leader on this one. Like I know that Ian can get with any of the girls, but that save requires that Jeremy be able to get with those same girls at some point. It's why that save file hasn't been updated in a year, just waiting for Jeremy to somehow manifest his "player attributes"
