[Something about that wording makes Demyx nervous. Oh no, if people start to think of him as a threat then they'll try to kill him. Surely Elsa will tell everyone. Better try to make it sound less bad]

Well, more like to help my group. What we're doing is very important for us, because it is...uuuh... [Okay, the odds anyone from the Organization will visit Elsa's world are rather low, so maybe he can tell a few details?] You see, I was attacked a long time ago and almost died, kind of survived but got my heart...stolen?

So I was taken into a group full of people who went through the same, and we all work to get our hearts back and, you know, get back to normal lives. That's what we do. And there was this member, he was our best fighter against the same creatures that took our hearts, but he betrayed us and is now with some teenager and his friends. And that's bad, so I thought Hades would have a way to get him back. Even if it was by sending something strong against him and -- knocking him out or something. Because we need his help. Kinda desperate measures, you know?

[There's really no way to make it sound completely good and he knows it, no matter how much he twists the truth. Everything they do is all for the benefit of the Organization, not really caring about how it affects the world around them. That sometimes their actions prevent trouble from happening, and that sometimes their actions plunge worlds into darkness and people die, well, nobody cares about that, Demyx included]
