With Felicity guiding him from the bunker, Oliver is forced to deal with a city that has become overrun with both criminals and a slew of new (and painfully inexperienced) vigilantes. Watching Oliver try to balance his jobs as both the mayor and also the protector of Star City, Felicity suggests he form a new team, but Oliver resists.
