Headscratchers / Santa Clarita Diet

• If Poplovic's goal is to keep a "live" member of the undead locked up to harvest their black tar blood, why does he kill his minion Vlado for not double-checking the arm cuffs and letting their undead prisoner kill himself? Couldn't he just infect Vlado with the undead man's fluids (pull a human stapler like Ron did with Gary, or stab him in the arm with the black goo covered knife like Sheila did to Loki, thereby making Vlado his "undead queen bee" without having to go all the way to Santa Clarita to search for a new one?
  • It may be possible that only "live" undead could spread the virus, and possibly only through a bite. A dead undead would be useless to him.
• If the FBI is able to identify Bob's DNA at the second fracking site explosion, wouldn't they also find pieces of the tarp he was wrapped in and be suspicious his already deceased body was planted (which it was)?
  • Very likely, the C4 either destroyed the tarp or burned it beyond recognition. Tarps would likely be far easier to burn than a human body.
