When Tilo makes "paan" for Kwesi, she is shown putting some betel nuts and finally a cardamom in the paan. However, upon revelation, a clove is seen in the paan which was never there before.
During the scene when Doug tells Tilo about his relationship to his mother, the glass of lemon soda that she gives him is full, then when he sets it down it's empty. Then he raises it again to his mouth, and it's full again.
Towards the end, Doug hits red chili peppers with his shoulder. The chili start turning. In the next shot they are still, and in the following one they are swinging.
