I agree with you about Sage. In EP7, Sage takes her role as president of the HOTs seriously again.
There could be problems between Bella and Jill if the MC is on both routes. My MC is not on either of their routes. Despite all this, my MC can help Jill and Bella because they are friends. Bella's is still changing for the better as well as Jill. But the Romitschen Scenen does not exist of course.
Lily, I think, will not be active in Quinn's drug ring. When I look at Lily's entire history, I theorize that Lily is spying on Quinn. The conversations between Lily and Quinn can be compared to an interrogation. Quinn is supposed to be the successor of Sage. Sage actually trusts Quinn, but is not 100% sure. You can read that in several conversations. In my opinion, Sage brought Lily to B&R with the help of Rusty. Quinn didn't want Lily at the HOT's, but Sage did. In EP7 there is a party scene of Lily and Sage, where they have a serious talk. Sage is also having a conversation with Josy and Josy has already grumbled at Quinn about the scavenger hunt list in EP6. Sage meets with Maya because she knows about everything. The air is getting thinner for Quinn. That Lily has the ambition to maybe become Sage's successor, I personally find okay. Lily takes care of her sisters.
