Beast Boy introduced the building to his fellow heroes as the headquarters of the Outsiders, complete with all kinds of equipment their team would need, like a mission room, separate rooms for everyone (including those not in the team), even an empty space reserved for a future Zeta-Tube.[1]
M'gann showed the Outsiders a video of a Reach warship in Brooklyn, and Beast Boy hit the Troub-Alert to summon the rest of the team. They then left for Brooklyn via the Zeta-Tube.[1]
After receiving intel on a meta-trafficking lab in Cuba, Beast Boy and Geo-Force took off for Happy Harbor via Zeta-Tube, to rendezvous with the rest of the Outsiders.[2]
Forager, Terra and Halo chose to remain at their school in Happy Harbor, which required them to get up at 4:30 to compensate for the time zone difference.[2]
In the Hub, the Outsiders were relaxing when Helena Sandsmark, Eduardo Dorado Sr., and Jay Garrick showed up to speak with their wards about their heroics. Garfield received a call for help by a girl in Ireland, so he, Blue Beetle, and Static left the Hub to help her.[3]
Kitchen: A fully stocked kitchen and eating area, overlooking the city.
Living quarters: A number of spacious separate bedrooms above the mission room, enough for everyone including those not in the team.
Med Bay: A room filled with advanced equipment to treat injured members.
Gymnasium: A room filled with exercise equipment and serves as a training area.
Mission Room: The central area of the headquarters, with a holographic computer interface, and a secured link to Watchtower systems. When not in use, the room could double as the Outsiders' "super stylin' living space".
