Trap x In The x Hole - S1.E17

Killua grows tired of having Imori shadowing him so he challenges Imori to a fight and quickly dispatches him. Meanwhile, Gon has joined up with Leorio and Kurapika. The three of them devise a plan for taking Ponzu's tag and track her down to a suspicious-looking cave. That is when Leorio insists on heading in alone.
