A mix of this and Tear Jerker, but Zidane telling Dagger about the man who tried to find his true home and came to realize that his true home was with his adopted father. (Aka, Zidane's first time he left Tantalus.)
Zidane: Once upon a time... ...there was a man. There was a man who didn't know where he came from...
Zidane: This man had longed to find his birthplace ever since he was a small child. His birthplace. A place he only remembered in his dreams...
Zidane: He wanted to know more about himself, maybe. About his place, the house where he was born... One day, the man left the home of his adoptive father and went on a quest to find the answer. His only clue was the blue light he saw in his dreams..."
Dagger: A blue light?
Zidane: Yeah. He thought it might be a memory of his birthplace. An ocean, maybe...?
Dagger: Did he find it?
Zidane: Hey, you're jumping ahead. A lot of things happened along the way. Alright, we can skip ahead... No, he never found it. How could he? His only clue was a colored light. So he went back to the home of his adoptive father... What do you think his father did when he came home?
Dagger: Welcomed him home?
Zidane: No way! The father raised his fist and beat the son he had worked so hard to raise.
Zidane: "I don't know... But you know what surprised him even more? The father smiled, after beating up his son! Can you believe that? He just gave his son a beating. But this is what the man thought when he saw his father smile... This is my home. This is the place I call home. The man is still searching for his birthplace. But he already has a home.
During the events of Burmecia, Vivi worries out loud that he might not be human. Cue Quina coming along with a surprisingly touching response.
Quina: I not human. But you, you definitely human.
- In the same vein as above, Steiner's interactions with Vivi. Steiner can be extremely obnoxious at the beginning of the game, so thankfully he gets a truckload of Character Development. The one thing that never changes, though, is how much respect he has for Vivi. The culmination of this is probably when they go to the wind temple together:
Steiner: (re: a giant wind dragon) You attack him with your magic while I hold him down!
Vivi: But...what if I miss the target?
Steiner: I trust you, Vivi.
*and then the two of them proceed to beat up Wind Guardian all by themselves*
