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...
There's no way you can defeat me 
with your heart in that state!
!مُحال أن تتمكّن من هزيمتي وقلبك بهذه الحالة
Und mit dieser Gesinnung willst du
mich besiegen? Lächerlich!
Es ridículo que creas
que así podrás vencerme.
Es ridículo que creas
que así podrás vencerme.
Vous ne pourrez pas me battre
dans cet état !
Non hai speranze di battermi 
con questa predisposizione mentale!
Não tem como ganhar
com essa falta de determinação!
И пока не осознаешь этого…
не победишь!
