Mari, too, is a Synth created in Lab 14. She has the ability to freeze time.
MORE BEFORE THIS. Her flaw, however, is that she can only hold it for a short while before it snaps back to the time when she froze it. Those affected by her freeze never know it happened, and are only left with an intense feeling of deja vu. However, if Mari is in contact with someone, directly or through another person, they will not be frozen, and can move about the still world with her until it is released once more. If not touched by her when the world is unfrozen, a person will snap back in time to the point where she froze it, also with no memory and the deja vu feeling. One must be touching Mari if they want to not be frozen or not be reset. Mari was Peter's lover later in life. Friendly yet timid, she becomes standoffish and borderline rude once Peter is killed, which is right before they leave for Redborough to find Shawn and Jaxon.
Peter, skimp on Shawn but maybe mention.
