The Exorcist
S02E07
Season 2 Episode 7

I like how we saw how the demon conquered Andy & how Andy was fighting it. The demon tried to turn Andy against the kids by making him remember Nikki saying mean things about the kids but that was not working. Andy kept fighting it because he was like 'that is not what happened' because Nikki would never say those things. 

Then the demon figured out that by making the kids responsible for Nikki's death, because they slowed him down from reaching her at the lake, it could turn him against the kids. It was pretty interesting.

Just as I suspected, the rock was in her pocket to weigh her down.
