Enter the Sandmouse - S0.E2

Mouse, Skillet, Golden Joe and Peanut Cop trek through the desert after leaving the city behind. However, Golden Joe is carried away by a bird and Peanut Cop later vanishes in a flash of light. Now alone in the desert, Fitz and Skillet live in a house made of sand and their own spit. They get into a gunfight with a strange, gun-toting woman named Lee. After the woman mentions something about Square Guy and finding the new angel (or "new age-el") Fitz decides to trust her and invites her into his house. Lee gives Fitz a gift: a silver bullet which she warns is the only thing that can kill her when she turns into the She-Wolf. After the credits, a gunshot is heard, and Lee (as the She-Wolf) appears snarling in front of the screen.
