I'm a guy, male yes. I don't know why someone called me she before lol. I had a Trumblr long time ago but I didn't really used it that much. What I use the most is twitter (@Keinart) so you can probably find me there.
Uhmm the Luce thing, that's again one of those things I would like to leave people to imagine, but I think something more "mature" and "masculine" would be kinda funny, wouldn't it? Something like Punch of the North Star or Jojo, it would be special and the kinda unexpected thing I would love to find out of someone like Luce.
And the Ziva thing, well, they were kids after all, so they really never had a true relationship as to be sure if they were in love with each other. It's that more pure love or just caring for an old friend? Ziva is the kind of responsible woman that takes care of everything she does by himself, it is mentioned a few times how she took all the work for the committee and some other things until everything would be perfect, so it wouldn't be weird to think that the thing Ziva had with Ciarán was more related to her sense of responsibility than actual love... or maybe not. Again I prefer people thinking about this.
Also her introduction without Ciar it's something like this: "Hi, I'm Ziva. I'm from the same class as Endyein. I love to study the human brain and I hope to become a psychologist one of these days." Kinda the normal introduction, isn't it? I think it's a lot better how it is right now, even if Ziva gets mad for it.
