I have an idea to add onto the "things that happen between Cass's search for a mommy."
In Batgirl issues 45-50, there's a drug called Soul. In issue 46, Cass ingests some and has small hallucinations, little representations of Batman, David, Barbara, etcetera.

I think it could make for an engaging sort of scene to write. With some different characters perhaps, although Batman and Barbara could be good visualisations of maybe her shame versus her urge to be cared for, maybe add a few other characters too? Steph, maybe? David could be good too as someone admonishing her for this.
I don't know, thoughts?
