When Nancy goes to ask Celia if they can use her house for a grow-house around 13:12, initially she has both hands on the cash Nancy gave her, but she covers the bandage on her neck with her hand. The camera angle changes to show Conrad's reaction to seeing her again and both of her hands are on the cash. The next shot, Celia's hand is on her neck again.
When Nancy and Conrad are at the grow house the damp spot on Conrad's t-shirt repeatedly disappears and reappears between shots.
