In the original timeline, Black manipulated Wenda, and everyone was being defeated by her. However, in this timeline, for some reason, everyone has "Wenda-fied," and the world is overflowing with crazed smiles. The sky is blood-red, and everyone is out for Wenda's life. You can choose to be Wenda-fied yourself or be one of those fleeing. Wenda is sane and terrified. Everyone else who has succumbed to the Wenda-fication approaches with a mad grin. The ending is up to you.
