If you're DIK, you may as well not even bother with Jill. I haven't looked at all of her scenes in the ep 7 script yet but every one i've seen involving the MC has conditional logic that breaks on DIK affinity.
DPC created a new variable, ep7_jill_jealous that caps out at a value of 2 depending on your status with Josy and Sage. From what I can see, it's only used to decide which scene fires off with Josy and Jill in the bathroom but you never know.
Regardless, if it turns out bad you can just enter "ep7_jill_jealous = 0" into the console and you're fine. It's not a persistent value so it'll probably be renamed if he does something with it in ep 8 tho
This is why we sail the high seas of the internets fam
