Turning 15, Will challenges Blood to a fight with real swords as his coming-of-age ceremony, but Gus asks Will to lose on purpose. Will doesn't get a chance to ask Gus about what happened that day in the ruins before he must head into his battle against Blood.
And don't forget to do good and pray.
ولا تنسَ أن تفعل خيراً وتصلّي
Und vergiss nicht,
Gutes zu tun und zu beten.
No olvides rezar y ser bueno.
No olvides rezar y ser bueno.
Et n’oublie jamais
de prier pour les autres.
E non dimenticare 
di fare del bene e pregare.
E não se esqueça de fazer o bem e orar.
