You don't get how stubborn Serah can be... I think she would have followed me in becoming Ragnarok, so I wouldn't be alone. She... She did so much, going through all those timelines, risking everything, just to see me again. I know Serah would do anything to let me know I wasn't alone. That she was always there, no matter what. If there was guilt, it would be both of us feeling it for not being able to prevent it from happening.

[She looks over her shoulder to where her sister was off screen.]

The only thing I feel guilty about is not being able to save her in the end.
