… which is actually her psychically communicating with Grandpa Zombie, who's providing a GPS assist to Doc and Addy, who are in hot pursuit. "Lucy!" the old geezer growls repeatedly, his bony finger pointing the way. It's both creepy and adorable.
Not too far behind is the rescue team consisting of Roberta, Murphy, Sun Mei, 10K, Red and 5K. They're on the road to Mount Casey thanks to the brilliant surveillance work of Kaya, who's a bit worried that she hasn't heard from Citizen Z in 12 hours.
A Zona SWAT team arrives and blows the zombies away, though the soldiers are looking the worse for wear as their glowing eyes reveal that they're losing their immunity. The Man tells them to arrange for air transportation to Zona for him and Lucy STAT.
The rescue team enters the mountain, ready to do battle with The Man. They traverse the catacomb-like structure but don't get very far before 10K collapses. Sun Mei reveals that in order to save 10K, they have to kill him … much in the same way that Murphy technically flatlined after he was attacked and bitten by zombies all those years ago.
Sun Mei, Red and 5K stay with 10K while Roberta, Murphy and Doc confront The Man and Lucy at the top of the mountain. Murphy and Lucy have a brief tender reunion before everyone starts shooting at each other.
