Tag Team Trial: Part 1 - S1-E10
Continuity mistake: After Chazz tells Chumley he is going to have a lot more room, Zane is shown staring at Jaden, Syrus and the Paradox Brothers. The next shot shows the brothers doing a monologue. As Para says "We didn't come to talk", Para stretches out his hand and Dox stretches out his hand at he same time. Dox's hand is shown to be placed directly in front of Para's hand in this shot, but by the next shot, their hands are more stretched out and are further away from each other. (00:06:15)
