[Lonely...

He'd never really spared the time to think about the word. It was true that no one he'd ever known would exist for quite a long time. From time to time he would wonder how they were doing, and what became of the future, but deep in his heart he still believed that they no longer needed him. Even if he wanted to return, his presence would bring nothing but trouble.

So as it was, he didn't yearn for them. And the one person he truly missed was already dead.

As for the people he met here... there were a few he could say he cared for, but even still he was a distant presence. He simply wasn't able to open up to them, whether it was because they were civilians, or for fear of creating a time paradox. His burdens were not theirs to bear.

Consciously, Zero couldn't say it bothered him day-to-day - his job kept him busy enough. But having no one that could understand his feelings... perhaps that was loneliness? He wasn't sure.

At least he had Croire.

After long deliberation, he could only come up with one response.]

...I don't know.
