Meanwhile, Green Arrow has taken a break from being a vigilante to be a father to William. The team is still on but without their leader it is chaos. There is only one way to save Star City: open up another breach inside S.T.A.R. Labs and travel to Star City to find Green Arrow and convince him to travel to another Earth to save his city.
