Elevator, Outside Catwalks
You'll need to talk to Biggs, and then Jessie, to open the two security doors here. Barret will join the party before you can do that. Don't miss the chest with a Phoenix Down in the southeast room. You'll need to talk to Jessie again to open the door to the Elevator.
Note that on your return trip, you'll need to help free Jessie in the Pipes area, or you won't be able to get past the doors in this area.
