Chicago Med left fans on a dark and scary note during the season 11 fall finale - and Dr. Caitlin Lenox's fate is still unknown. Showrunner Allen MacDonald played coy about whether fans should be "worried" about Lenox (Sarah Ramos) surviving the season, exclusively telling Us Weekly the team wanted to "keep it a complete mystery" after her dramatic cliffhanger. "I will say that we do a time jump. We don't just pick right up where we left off. We jump ahead two days," MacDonald confirmed ahead of the show's winter return on Wednesday, January 7.
