And on further thought. I will flat out say I think she's lying about a) the incident with Elliot when Morgan was younger or b) ever thinking anybody else was around her house at night besides him.
It's just too fantastic to think this happened when he lived around them and THEN as soon as he moves across the street there is a stalker and they suspect ANYONE other than him EVER. Or that they EVER talked to him about anything let alone let HIM pick the suspect that they continue to obsess over. I call bullshit.
