While I, too, want Cath to walk off into the sunset of casino management, if she was blown up real good she technically wouldn't have to leave in a body bag.
Or she could be alive but walk out of the lab in a body bag, kinda like how you cocoon yourself in your sleeping bag and hop.
Speaking purely as a Cath fan i'm slightly nervous about all these lose ends that need to be dealt with e.g. haskell and sqweegel. Both in terms of Cath being the target and whether we'll get a Cath-centric episode before she leaves.
If this really is her last season i expected us to of had more of a build up to it than we have this season, maybe she'll end up taking both Sqweegel and Haskell down
