Kaylie Russell: I found it.
Tim Russell: What do you mean?
Kaylie Russell: We only have few days.
Tim Russell: A few days for what?
Kaylie Russell: To keep our promise. And kill it.
Alan Russell: I've met my demons and they are many. I've seen the devil, and he is me.
Tim Russell: It was the mirror.
Chosen answer: Tim was the one accused of murdering his father. His sister was deemed a victim of Tim's neurosis. He tried to defend his actions by blaming it all on the mirror which made him appear to be crazy. His sister was not accused of any actions she'd need to defend herself against and so was able to avoid the scrutiny of medical professionals.
