I don´t think Sage has paranoia. It´s not paranoia if you are right about your fears. I don´t think that DPC is going to make another 180º change of direction for Sage, from "I don´t care if you date or fuck others" and "Let´s fuck Quinn, you and me" to irrational jealousy.
I think the relationship with Sage will be ruined if Tremolo fucked with her mom. Maybe there will be another situation like "tell her or not that her ex is gay", but this time with her father´s business with Quinn, if (or better, when) Tremolo discovers it. And maybe DPC set another booby trap in the path of Tremolo that we don´t know already and will potentially make explode Sage´s relationship. But I don´t think Sage is going to start behaving like a crazy possessive girlfriend.
I'd be surprised if Sage behaved differently. She has already admitted that it is very difficult for her to let go. And if you reject her at the end of episode 8, she admits that this is for the best since she has already begun to get attached to him and did not want to lose his friendship. She gradually falls in love with him and this is the most inconspicuous process unlike other girls and I like it. Because their friendship is really often very difficult to distinguish from a real relationship.
I would definitely like to see Sage as possessive and jealous of every girl. But having sex with Quinn raises a big question. In the future, their relationship is likely to be similar to Heather's relationship with Tommy, but healthier and more trusting. Sage will become a light version of Heather in the future.
I personally don't think Jade's problem is significant.
Firstly, if it turns out that MС fucked her, it will primarily hit on Jade and her reputation.
Secondly, despite the fact that she took the breakup quite negatively, I think the maximum that she can do is to talk negatively about Tremolo, that he uses Sage and provoke a breakup. Probably at some point she will try to seduce him. But I am sure that sex with Jade in the past episodes will not cause Sage and MС to break up. Otherwise, the radical diks will have only one branch of the Others, and I think DPC gives MC a chance to correct itself.
Thirdly, Quinn's problem seems to me much more significant.A clash between Quinn and Sage seems inevitable. Quinn says in episode 8 that when she becomes the head of Hots there will be changes and Sage will definitely soon find out the truth about the secret brothel within the walls of Hots. MS can tell her the truth and side with her, confront Quinn, or side with Quinn. This choice seems to be the only logical way to end any relationship with Sage.
In general, as already noted, MС rejects only Jade, but does not reject Lily, Envy and others. MС will be able to explain that sex with Jade was in the past and Sage already knew that MC was popular in this times and fucked many girls and will be able to forgive him. Besides, Tremolo didn't know she was Sage's mother. Perhaps they will break up for a while and if MС plays the cards right, they will start dating again.
I am sure that past relationships will not matter as much as infidelities during a relationship. The connection with Jade makes sense for dramatic effect, the entire ending of episode 8 comes from the assumption that the player on the way Sage fucked Jade. To end such an intrigue with a banal parting is too stupid.
