Ep 23. Medieval Knight Adventure

Jett and Traver deliver a knight costume to Esteban, who wants to play knights and dragons. Traver takes them to the Middle Ages, where they meet Sir Nigel and face a 'dragon' that's actually a friendly lizard. When the castle starts collapsing, Traver rebuilds it with his time-reversing powers. They return to the present with Esteban's new 'dragon' friend.
