"What are you doing here?" Evee asked her father, "You shouldn't be here after…you know."
"After my partner decided to leave me, you mean?" Eren responded to his daughter with a sad smile.
Evee was uncomfortable. She had been very close to her Curse, but the relationship between Eren and his Curse was different. And, to make things worse, Evee's Curse decided to stay with her. The Rainbow Dragon might not be a Curse anymore but she stayed with Evee for research purposes. The Rainbow Dragon wasn't present right now. It was out visiting some of her distant family – those who were still alive – but Evee didn't mind. She was busy either way.
"I feel useless," Eren grumbled, "I still don't understand why the Curses left us or how some of them stayed with Curse Users. Even Selena's Hydra didn't separate its full Essence. Some of it stayed behind with the Nest Leader. So why did my friend and lifelong partner leave?"
