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...
I think I can see the pain 
in that man's sword.
أظنّني أستطيع رؤية الألم في سيف ذلك الرّجل
Ich erkenne das Leid in dem
Schwert, das er führt.
L’épée du héros a l’air de souffrir.
Ho l'impressione che la spada
 di quell'uomo stia soffrendo.
Acho que posso ver o
sofrimento na espada dele.
Я будто вижу…
как меч плачет у него в руках.
