IGN: Mission accomplished! Murphy has been handed over to the last remnants of the CDC and the vaccine that will save the world will now be delivered to the masses! Well, if it only were that easy. The Season 2 finale of Z Nation, “All Good Things Must Come to an End” is an ending of sorts as we see Warren and her group appear to successfully complete their mission when they hand over The Murphy to an organization claiming to be working on behalf of the Center for Disease Control. Of course, nothing is what it seems in Z Nation land and just as things are coming to an end it looks like they are only getting started.
