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.
I promised I'd tell you once you grew up.
وعدتُك أن أخبرك حالما تكبر
Ich habe versprochen, es dir zu erzählen,
wenn du erwachsen bist.
Prometí contártelo cuando crecieras.
Prometí contártelo cuando crecieras.
Je t’avais promis
de tout te révéler.
Ti avevo promesso di dirti tutto
 una volta che fossi cresciuto.
Eu prometi que contaria
quando você crescesse.
Я обещал рассказать,
когда подрастёшь.
