Meanwhile the plane crash on the Island and the Joker becomes one of the survivers. On the second season our losties got Ben and prisoned him in the hatch for to interrogate and this time they gave this duty to Joker instead of Sayid. What do you think? What would happen? Did Ben tell all the secrets of The Island in a second??the joker asks to Ben; why are you so serious?? Lets put a smile on your face!
