When Sanya Patel visits her old town over Thanksgiving break, she immediately falls for Steve Harrington. But only until she practically runs over what is thought to be Billy Hargrove. After a meeting with the kids and a quick rundown of the events that have plagued Hawkins, Sanya begins to put two-and-two together. Billy had been stuck in the Upside Down while his alter ego took his place as a minion of the Mind Flayer last summer. But can the real Billy go back to his normal life in Hawkins? Or will the trauma be too much?
