The variable "ep11_bianca_path" tells me something else. Hehe!
Bianca won't have a solo path for her... it does not make sense. That switch is probably us getting her contact and getting some flirting and nudes.
For me, the only way we get in a relationship with Bianca is in a throuple with Jill and being completely honest with it, it's actually possible. Jill is not the jealous type, even when we invite her back home to meet Neil and tell her about the plans to meet up with Zoey, she is more weirded out than jealous. To get to Bianca's scene you literally make choices that rises Jill's points, that's a bit telling.
Also Jill is, maybe, into both Bella and Bianca. And she is getting more wild with time as well.
