Continuity mistake: When John sees his photos on Sarah's website, the lower row of photos shows him throwing a football. However, when Sarah took those photos earlier, she only took out her camera AFTER he threw the football, while John was already talking to Sam.
Continuity mistake: After John has had dinner with Sarah and her family, when they are standing in Sarah's room, the amount of hair tucked behind Sarah's ear changes repeatedly between shots.
Continuity mistake: When we first are introduced to John on the Waverider we are shown his pendant swinging freely in front of his life vest. However in the shots after we do not see the pendant (or the chain if it was put into his lifejacket) including the flip on the wake. However when he pulls back up to the beach and takes off the vest the pendant magically reappears.
Continuity mistake: Towards the end while John, number 6 and the boy are leaving the town the sun changes between shots.
