When Jessica is first talking to her cousin Cal in the police station, Cal doesn't have a pen in his shirt pocket. By the time the lawyer, Mitch Payne, enters the station and begins to engage in conversation with Jessica and Cal, a pen has mysteriously appeared in Cal's shirt pocket.
When Jessica first enters her cousin Cal's apartment, the blue stripe ticking on the pillow he is laying on is exposed. After Jessica enters and Cal is still asleep, the pillowcase completely covers the pillow and no ticking is showing.
