*MAJOR SPOILERS – ENDING*
Garnet is watching the play "I want to be your canary" and as you saw, Zidane was in disguise and then showed himself. Garnet then makes to run out, and Steiner and Beatrix let her go. She runs down the stairs, and out to the street. After dodging and bumping into a few people, someone knocks her and her pendant falls to the ground. She stares at it for a sec and then runs out and nearly tackles Zidane over with a hug. They stare at each other and hug again. She bangs her fist against his shoulder a few times and then you see all the vivis, and the other main characters cheering and clapping. Then Steiner and Beatrix hold up the Save the Queen blade and the screen fades. Then the screen says:
"How did you survive?"
"I didn’t have a choice"
"I had to live"
"I wanted to come home to you"
"So…"
"I sang your song"
"Our song"
Then it shows a panoramic view of Alexandria followed by the credits that show random in-game FMVs on either side to the song of Melodies of Life and the Ending FF theme.
Enjoy 😛
