NATALIE: The machine that will seemingly destroy one universe over the other continues to be simultaneously built in both realities. "There is an enormous focus on how that thing can be activated and what it will take to do that, how it can be finished, and if it is, what are the implications," J.J. Abrams tells us. The key element for the machine to work is Peter. "Peter is the only person who can power that machine," Jasika Nicole says. "That's really integral into which universe is going to survive. It's going to rest on Peter's shoulders."
