Where is Julie Purcell? And is she really still alive?
The biggest revelation at the end of the first episode is that Julie Purcell, the little girl presumed murdered, is still alive in 1990. Or at least her fingerprints have been recovered at the scene of a a robbery. It's unclear whether she was a participant in the crime or simply at the location where it took place, but it throws a wrench into the story we think we are watching. It's no longer just a search for a murderer -- it's also a hunt for the truth about what became of Julie. Late in episode two, Elisa mentions "after the events of 1990 and what happened with Julie and her father." Now that we're nearing the end of the mystery we know what that means.
During the 1990 investigation, Tom Purcell (Scoot McNairy) appears on TV to plead for his daughter's safe return. That results in someone who sure sounds like Julie reaching out, but she's not seeking to connect with her dad. Instead, she wants the man on TV to "leave [her] alone," and claims they left Will "resting." Naturally, Tom becomes a suspect, but he maintains his innocence, going on an investigative hunt himself. This leads him to the Hoyt family mansion, where he encounters a pink room. His last word is "Julie" before the Hoyts' suspicious security officer, Harris James -- formerly a member of the force who processed the Woodard scene in 1980 -- appears. The next thing we know, Tom is dead next to a typed suicide note, but it seems pretty evident that Harris killed him.
Unfortunately, there are still lingering questions. Did Tom or any other member of the extended Purcell family have any relation to Hoyt? Did one of her parents "sell [her and Will] off," as Elisa suggests? And what about those questions of Julie's parentage that her grandmother raises? And what of the detail that Tom was likely gay? Could he have been blackmailed?
