Detention Adventure: Season 3, Episode 7

3 - 7: Kinetic Expression

Raign's realisation brings the Team back to the Forbidden Valley, where the team uses sound waves and teamwork to discover an actual treasure chest! Inside is a deed that declares the whole island was owned by Lawren Harris, as well as the original paintings from each corner to prove it - the kids are crowned heroes again, and their time at Island School comes to an end. Everyone is happy with the result... except Kelly, who doesn't think the mystery adds up.
