Team Arrow finally took down Damien Darhk in season 4 finale. Unlike the mystery death teased in the midseason finale that gave Oliver and friends a reason to put on their suits, in the May 25 episode titled “Schism” their biggest problem has been solved.
In the aftermath of the showdown, [SPOILER ALERT!] the members of the team decided to take their separate ways. With his suspension from the police force now a little more permanent, Quentin’s heading out of town with Donna. Thea also announced that she would be leaving Team Arrow to find out who she really is, after threatening to kill a little girl, Darhk’s daughter, to save her brother.
