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...
the things you've lost wouldn't come back.
الأشياء الّتي فقدتَها لن تعود
no recuperarás lo que has perdido.
no recuperarás lo que has perdido.
ne fera pas revenir les défunts.
non ritroverai ciò che hai perduto.
o que foi perdido não volta.
то, что потерял, уже не вернёшь.
