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...
But these guys were weak! 
That's why we lost!
!لكن كان هؤلاء ضُعفاء! لهذا خسِرنا
Pero ellos eran débiles.
Pero ellos eran débiles.
On a perdu
parce qu’ils sont tous faibles.
E invece questa gente era debole, 
per questo abbiamo perso.
Mas eles são fracos!
Por isso perdemos!
Чего они такие слабые?!
Я из-за них проиграл!
