Episode 4 of The Woman in the House Across the Street from the Girl in the Window opens with a haunting flashback to the fateful events at the lake. Meredith's anxiety mounted as she watched Emma swimming alone, while Neil's mood darkened, revealing the cracks in their marriage. Losing his composure, Neil hurled curses at her, and in a moment of rage, pushed her into the depths of the lake. Did she perish, or was it merely a deathly illusion?
Anna jolted awake, realizing it was all a vision. Yet, her resolve to uncover the truth grew stronger, driven by a burning desire to expose Neil's alleged sinister deeds. Her investigation led her to Hillary Lathan, Meredith's sister, a resident of Middlebury, a trail that promised more insight. Anna located Hillary's address through social media and arrived with a casserole in hand.
Hillary revealed that she had suspected Neil of cheating on Meredith. Moreover, there was another tragedy that followed the initial one, involving Emma's school teacher who fell during a field trip to the lighthouse, where Neil was the chaperone.
Returning to the town, Anna spotted Neil carrying a foreboding bag and decided to tail him. However, Neil was aware of her intentions and confronted her for snooping. Anna stumbled but persisted, probing about the scar on his stomach. It was then that the context of the scar emerged—a failed kidney donation to his brother, a painful memory Neil relived with discomfort under Anna's persistent questioning.
To solidify her theory, Anna insisted on examining the contents of the bag. Inside was a ventriloquist dummy, a macabre companion that Neil used to cope with his grief after Meredith's demise. He moonlighted as a ventriloquist, finding solace in this unusual act.
On her way home, Anna received the results of her background checks. Lisa's record remained clean, but Rex's criminal history stretched far back. Suddenly, Rex appeared from behind, forcing Anna inside the house, leaving the viewer to wonder how far his criminal past truly extends.
