When Kaldur, Wally, Dick, and Artemis meet at the end, Artemis is given a magic charm that makes her look like someone else to everyone except the four of them. They show Artemis and a reflection of her in a puddle that looks different to establish the charm's effect. However, the puddle is positioned on the far side of Artemis. To see her reflection in the puddle, it would have to be closer to the "camera" than the subject.
