Deux Amours - S1-E5
Continuity mistake: Daryl fights the walker on the ship after it kills the other prisoner. He gets backed into a corner and jumps off the boat just as the explosions are happening. The walker he was fighting disappears.
Vouloir, C'est Pouvoir - S2-E5
Continuity mistake: When the car's engine breaks down, Daryl opens the back door of the car to get his backpack, and the car door slowly closes after he gets out. In the next shot, seconds later, the door is completely open. (00:00:40)
