The show opens with Mare getting a call from one of the town's elderly members, Mrs. Carroll, who informs her of a creepy prowler lurking outside their house. While it may seem like nothing at first glance, we see Mare passing by an anonymous male suspect later in the episode, who perfectly fits the earlier description. With the fourth episode indicating an active sex trafficking ring in Easttown, it is a possibility that the Peeping Tom is none other than the van-driving kidnapper who's been picking up women – Katie Bailey and Missy Sager (that we know of).
