Please spoil this for me (no sarcasm!)

I watched this on AMC this morning right up until I had to leave for work. I'm really curious (sad, I know). Did the half-dead lady the evil female scientist kicked away from her survive? Or was she never shown again? What about the other girl (blonde, with glasses) that was with the villainous woman and the fat Welsh guy and the hunter? She seemed kind of like an "innocent bystander" to their schemes and I wanted her to survive. The geeky kid and the Hispanic girl were kind of charming too. I guess it's beside the point to develop any real sympathy for or connection to the "characters" in films like this, as they're just thrown on stage to be eaten, etc. (Which is what I'm assuming happened) I'm sure the evil scientist and her boss got eaten. You could see that coming before the cat even escaped.
