Charlotte Hale
First, let’s remember that the real Charlotte Hale is dead. And this Host, while in Charlotte’s body, is actually a copy of Dolores—one that went rogue after Charlotte’s memories started bleeding into her own, Serac had Charlotte’s family killed, and the real Dolores abandoned her. The new Charlotte ended season three by having William seemingly killed by a Host replica, clearly planning on Killing All Humans to make the world safe for Hosts in season four.
