I'm weak because I've failed you. [If Gai really did do the things that he says he did, then Shu's failed. He shouldn't have had to go that far to put a stop to the Apocalypse.]

No, that's not true. I've failed everyone including myself. What's there to believe in? [Shu still doesn't see it because he lowly of himself.]

You shouldn't even be concerning yourself with me. Focus on yourself. [He's trying so hard to sound like Gai. ]
