Head northeast from Tears’ Point (or east from Esthar City) to get to the Lunar Gate. Enter the complex then follow the girl who says she’s been waiting for you. Angelo runs in and Squall assures the dog that Rinoa will be okay. Inside the chamber, follow the staff member to an orange capsule, where he’ll brief the party on their upcoming space journey. Zell volunteers to stay behind and look after Edea. Choose to trust him then form a party consisting of Squall, Rinoa and another companion (other than Zell and Edea). You won’t be doing much fighting up in space, so select whoever needs the least leveling up. Move Squall inside the capsule and watch the blast-off sequence.

When you take control of Zell, exit the complex. Select a 3rd party member to join Edea and Zell - then head back to Esthar City (remember to junction everyone).
