Head in the Clouds: Part 1 - S3-E7
Deliberate mistake: Chazz and Adrian take part in a duel where they stand on glass platforms that are suspended in the air, held by helicopters flying above them and are positioned at least a hundred meters apart. They appear to have no problem communicating back and forth, despite the large distance between the two and the helicopter rotors loudly spinning above them.
Head in the Clouds: Part 1 - S3-E7
Deliberate mistake: Adrian walks outside the Obelisk Blue dorm to see Chazz standing on a glass platform held up by four cables on each corner, which are attached to a helicopter flying above. Adrian then realises he is standing on a glass platform, held by cables and attached to a helicopter. There is no way he wouldn't have noticed this; he should've seen the cables, heard the helicopter and felt the glass platform beneath him when he walked onto it, even if it makes for a cool reveal.
