How is Dexter escaping from the hospital ???

I need scenarios whos the got the best theory for how Dexter gets out of this one. How does Resurrection go ? Does he kill his way out of the hospital ? Does Angel turn up and help him ? Does Angela just say screw it im helping too ? Does Harrison come back and just kill everyone in the hospital with that rifle and bust his dad out of there ?

Whos got something for me ?
