Are you saying that ultimately there 
was no need to gather the keys?
أتقصد أنّه لم يكن هناك داعٍ لجمع المفاتيح في النّهاية؟
Also war es letztendlich nicht notwendig,
nach den Schlüsseln zu suchen?
¿Significa que lo de reunir las llaves
no tenía ningún propósito?
Ça signifie qu’il ne fallait pas
spécialement rassembler les clés ?
Stai dicendo che non c'era bisogno 
di raccogliere le chiavi?
Está dizendo que não era
necessário juntar chaves?
Хотите сказать, что в сборе ключей
не было никакого смысла?
