[In stark contrast, Lucy doesn't seem as traumatized by the incident.]

Yeah, I'm okay both physically and mentally. I've been through worse.

[She was asleep for the first half of it, since Nyuu had been the one in control when it started. During one of the lurches, Nyuu had hit her head, so that combined with the fear she felt, triggered Lucy to awaken.]

Really? But why did you grow up away from your homeland?

[She's genuinely curious to hear more about this melodic language of Mizuki's race. But she'll answer his question first.]

I never thought about it before, but... I did sing one song just before I arrived here. It was a short opera song and in a foreign language. I surprised myself.

[It's a memory that brings a flood of complicated emotions to Lucy's mind. On the bright side she saved Kouta, but by pushing her power to the max she'd destroyed her own body in the process. Yet she doesn't allow those mixed emotions to be easily seen on her face. The only thing she allows is a distant look in her eyes.]

I don't even know why I sang it in the first place. It just came to me.

[Maybe as a way to say goodbye to Kouta? She's not even sure how she could've known the words to the song, since it was Nyuu who had learned them from Nozomi. Then again, she and Nyuu were probably the closest to being a single personality again in their last moments of life than they ever were.]
