Nice Josy-based prophecy
I think you and others are right, we're getting a solo Josy path. How that happens is super unclear though. The most obvious thing I've thought of that could happen is Maya breaks up with Josy because she doesn't want to drag her down with the issues with her dad. But why Josy would accept that breakup and not try to help Maya out is the issue. There is clearly a big divide between Josy and Maya being caused by the dad issue, but any way you slice it, if Maya and Josy break up because of it then that's basically the villain winning and I don't think DPC will go that route. In other words, I think it's really unlikely that the falling out that you allude to will be caused by the current issues with Maya's dad.
If that's correct then it means we'll likely have to wait until the current daddy issues resolve to get another shot at solo Josy, which could take a few more episodes and possibly be tied in with whatever dramatic plot Josy must be getting in the future. You're also correct that Josy has zero drama as an LI, and the only drama that Josy herself has been involved in has been not getting into college, which was resolved, and the throuple drama, which was resolved. She really has no active story hooks for herself, except the fact that she's in the HOTs and Maya isn't. Josy could very easily come into some drama being in the HOTs by getting caught up somehow in the drugs/prostitution/something else so there's that.
I really want Josy as a DIK LI, my massive DIK MC needs his exclusive midget party girl by his side
