Decision x Shortcut x Long Way

The ship's captain recommends they go towards a tree on the top of a mountain instead of directly at their goal. Leorio takes the bus and the rest head towards the tree. The bus is a trap, so Leorio abandons it and catches up with Gon and Kurapika. Matthew, an examinee they meet, travels with them and then betrays them. They successfully answer a riddle asked by an examiner and move on to the next test.
