[Hiro says that like it should be obvious, but it's nothing of the sort to Leon, which... he's going to show off just now, because he's a paranoid child.]

Information like that is power over someone else. While I do not expect that it will cause too much trouble [because it's not like people should care that he's dead] it is nonetheless something that I would prefer to keep unsaid as much as possible.

[And goodness knows Leon's used to people using his weak points against him; this time, he's trying to nip it in the bud.]

So don't say anything about it. It would be better to forget what you thought entirely.

[Are you kidding, didn't you see him threaten that alien, he's not afraid to resort to beating people up--though he hasn't resorted to threats just yet.]
