They find their way into the bunker through a direct homage to Raiders of the Lost Ark. With the ex-President in tow, they look for a way to shut down the fourth strike weapon using his thumbprints.

What the team finds, of course, is a place full of zombies who were trained to kill kill kill. (Really. There's even a sign that says that.) Also in this bunker? That spooky old man from Zona. He's been trying to make Black Rainbow happen all along.

And then…twist! A flashback reveals where Roberta's visions have been coming from all season. It turns out that while she was in that coma, Dr. Teller woke her up and gave her all kinds of training to defeat the zombie-apocalypse.

All the visions she's had throughout have been the result of her training. The canisters, how to put them where they need to go, where she was headed all along - it was all implanted in her brain by Doctor Teller. The canisters are the cure for the virus! To be spread worldwide!

In flashback, Doctor Teller shows Warren the canisters. She's been collecting them and imagining them all along, and now the time has come to load them into the drone and send them on their way to cure everyone.
360543
Knowing what she has to do, Warren instructs Murphy and Doc to launch the code when she sends the signal, and then says goodbye to the team. She always knew this would be a one-way trip.
360544
The team do as their told and the countdown begins, but something's not right. Murphy isn't ready to let Warren leave, they've all seen too much together.
360545
And that's when Roberta remembers the truth. That while Dr. Teller told her that she was the answer to everyone's prayers, all that training had been so that she could deliver the reset, the Black Rainbow, and set every living thing in the world on fire.
360546
As Murphy battles the dude from Zona, the team watch as Warren climbs into the drone to try and unhook the canister, but she's too late…
360547
The black rainbow comes to pass. And as Doc and Murphy decide to watch the world burn, Sarge and 10K decide to have sex on the floor. And Warren…
360548
Warren is lost to the desert in the drone. Is this…the end of Operation Bitemark?
