In the comics she's a c-list hero called Hellcat, who nobody cares about. But in the context of this show we could be seeing a POSSIBLE villain or at least protagonist Hellcat for a Jessica vs Trish. Assuming Defenders 2 comes out before JJ S3, it could also be a central arc there instead. Trish's life is pretty much fucked and with her wish finally granted, she may jump head first into vigilantism costume and all. But this show being what it is, and not knowing the true nature of her abilities yet, it can go a lot of ways.
