Well, Selina used Elliot as a punching bag for quite a while, and then used him to get around some poachers, before finally having enough and sending him on his way with two 'guides', who were promptly revealed to be Dick and Tim, who immediately imprisoned him in Wayne Tower. That's where he is at the moment, supposedly, although future solicits say he's breaking loose and making all sorts of trouble using Bruce Wayne's face.
Selina, meanwhile, has finally made her way back to Gotham and is appearing in Battle for the Cowl, where she's naturally not on Jason Todd's side.
