Recently, the deceased Oliver Queen returned from a desert island where he spent 5 years. It is not surprising that he has changed a lot during this time.
You always had a strange relationship with him, sometimes a overfriendship, sometimes a underrelations. You were glad that he didn't die, but your attempts to talk to him failed. He pushed away everyone who cared about him or who cared about him, and you decided not to bother him anymore.
But at some point, a few days after everything, you find him on the doorstep. In fact, you didn't really want to see him anymore, because he told you to stay away from him, but in the end he comes to you himself.
One way or another, you let him into your apartment, not knowing why or what for. And I don't know how it happened, but here he is, standing in front of you, deciding to trust you and unbuttoning his shirt he shows you his scars, obtained on that island.
