I'm....trying to be cautious? [ That's mostly why she brought it up with him, and why she'll try to get information out of Tony, and why she worries about this in her spare time.

Because she might be wrong about trusting him, and it would hurt more than just her. ]

I think I don't know for sure if he wouldn't hurt people for the sake of his "justice" or people he cared about. Even without all the cube stuff which I don't really get. [ She uses one of Smoker's terms without really thinking about it, because Ikki isn't sure how else to explain it. ] But I also don't think he would hurt the people he does like. He seems to talk to a lot of people and is friendly, but to me he only mentions a few names, and those are the people I think he's close to.
