"So you came here a week ago, huh? I thought your Utopia exploration was over a few weeks back. Something must have taken your time. What was it?"
Eren asked while devouring another pancake covered in maple syrup. He had been talking with Nina ever since he had gotten fresh and came back downstairs. He was done narrating his side of the story. His version of what really happened anyway.
Nina could tell Eren wasn't completely fine. Sometimes his fluctuating mana signature would leak, showing his agitation. So she had asked him about it.
Eren came clean in saying that he had been suffering from a few nightmares. Of course, he couldn't tell her everything. Therefore, he blamed his condition on post-battle mental stress and trauma, which Nina believed.
She told him it was very normal for every ranker. She knew it was part of their growth process. She also felt satisfied that Eren had shared his fears and his vulnerability with her.
