The bloody hand on Dora's stomach appears and disappear from one scene to the next.
Dora and Luke decide that Luke will pick Dora up at her home at 6:30PM. Time passes and after a while Dora calls Luke to ask when he'll be there, indicating that it's already past 6:30PM. But when she looks at her phone after the call ends, it clearly shows 4:49 PM--almost 90 minutes before Luke was supposed to pick her up.
