Haruki collapses after saying goodbye to Kasuza, and Setsuna, who he betrayed, comes to take care of him.  Haruki is too overcome with guilt to move, and Setsuna tries to pretend she knows nothing as she struggles with guilt of her own.

Esto no es lo que 
tendría que haber pasado.
Ça n’aurait pas dû 
se passer comme ça.
Não era para ser assim.
