23. Lian Yu

Complete story — includes the ending

Oliver recruits a Mirakuru-less and hate-free Slade Wilson. Harkness is also recruited, but he quickly defects to Chase. Oliver's group frees Felicity, Thea, Curtis, and Samantha Clayton and traps Evelyn. Oliver asks Malcolm to take Felicity's group to Chase's plane in order to escape and manages to free John, Rene, Dinah, and Quentin, who knocks Black Siren unconscious while Nyssa defeats Talia. Malcolm kills Harkness, but sacrifices himself by taking Thea's place on a tripped landmine, allowing Felicity's group to escape. They reach the plane, but learn that the whole island is rigged with C-4 explosives, which will detonate if Chase dies. Oliver asks John to lead the others to Felicity's group and escape while Oliver captures Chase on a boat and frees William, who learns that his father is the Green Arrow. The plane is sabotaged, so Oliver tells the others to run to a ship on the opposite side of the island. Chase kills himself in front of Oliver and William, causing the bombs to demolish Lian Yu and leaving them unsure of the others' fates. In flashbacks, Oliver kills Kovar and his men, reaches the boat in time and calls his mother, Moira, on his way home.
