When the flower arrangements first came into view (when Jason goes out the door) the cross made out of flowers is at the right side of the corridor; seconds later Alicia comes to the door and that same cross is behind Grace, on the left side, and the flowers originally behind her are now on the right. Finally, when Alicia takes cross to move it inside, it reappears on the right side of the door again.
At 11:00 when Zach is introducing Hannah and the camera is facing Alicia, Hannah says "I know I'm older" but her mouth doesn't move.
