Lloyd's speech after beating Kratos in their duel in front of Origin's seal.
Kratos: You've grown strong.
Lloyd: Thanks to you.
Kratos: Aren't you going to finish me?
Lloyd: I defeated Kratos, the angel who betrayed us. And I forgive Kratos, the hero of the Ancient War, who helped us. That's all.
The entirety of Welgaia and Lloyd rescuing the party members from their respective phantoms that attack their flaws. They break out because despite whatever flaws they have, Lloyd accepts them for who they are no matter what. The best examples of this is Genis & Raine. As well as Kratos.
Kratos: Begone phantom! My son needs me!
Kratos' Taking the Bullet moment. It's just after it's been revealed that he's Lloyd's father. He blocks an energy blast from Yuan, and asks Lloyd, "are you alright...? Good." and then passes out. And now his cryptic "Don't die, Lloyd" starts to make sense, and we get the horrible creeping feeling he's been struggling to help Lloyd from the shadows all along.
In return, every time after this scene where Lloyd calls Kratos "dad" also counts.
