He lost his memories so she could not put it past him for not remembering her- for not remembering their times spent together; all the late nights cuddling and talking about nothing in particular. He didn't remember any of it, and she was doomed to remember it all.
Maybe a part of her hoped that seeing her in penacony would spark some memories within him. Sadly that wasn't the case- he looked at her like a total stranger and bought the lies she had to feed him. Caelus was still the same old- odd, funny and kindhearted. He was just as she remembered him. But he didn't remember her.
Maybe he could get to know her again. Maybe he could get to know Firefly again and they can rekindle what they had before. Even though this was not her purpose for coming to penacony, maybe there was some hope remaining for them.
Or not- for someone who had experienced multiple deaths, the heartbreak of seeing Caelus with another hurt more than anything. He had moved on... or could it even be considered moving on if he had no memory of her in the first place? Regardless, she felt replaced by the dark haired man. There was a burning feeling of longing and envy as she watched Caelus drag him around, the other man sighing at his shenanigans yet at the same time smiling fondly at the grey haired man.
Caelus seemed just as taken by his new lover. He looked at him the same way he used to look at her. She wanted that back. She wanted him back.
But, she could not be so selfish. His future with the Astral Express was brighter than his future with the Stellaron Hunters. Not to mention, she fulfilled her script and could now leave penacony.
At least she could see him one more time. At least she had the reassurance that he was happy and doing well for himself. She could leave now, with all the new memories that they had made together and the curse of remembering the old ones.
