First encounter with spirit ... and the knife - Wat?
*No spoilers here as everything noted is in the Trailer*
The ghost shows up the first time. She leaves the bedroom. Runs down the stairs. Unlocks the door with her 'RIGHT' hand. Opens the door runs onto the sidewalk where she now has a knife in her 'RIGHT' hand.
Its nothing special - but it is a great editing mistake.
