Ren is haunted by the deaths of his party members in a failed attempt to defeat the Spirit Tortoise, and doesn't want to believe that he might be responsible for what happened.  Myne seems ready to take his side and support him, but...
At first, I didn't believe her either.
في البداية، لم أُصدّقْها أيضاً
Zuerst habe ich ihr nicht geglaubt.
Al principio desconfié de ella.
Al principio no la creí.
Au début,
je refusais d’écouter cette femme.
All'inizio nemmeno io le credevo.
No começo, eu também
não estava acreditando.
Сначала… я тоже не хотел ей верить.
