Oliver thought you died. You met on Lian-Yu many years ago when he helped you escape from mercenaries that flooded island. Since then, two of you have been trying to return home. Until one day you were ambushed and blast wave threw you off the cliff. Long time passed, he returned to Star City and embarked on the path of vigilante. Today, he came to Central City to help Flash capture new metahuman. Everything inside him turned upside down when Barry showed him a photo of their target. It was you.
