[A world where everyone can be happy and successful... isn't that the world he wanted to build long ago, before Martel died? Before everyone had fallen into despair, and he found himself following Yuan blindly out of both grief and rage, just for a chance to see his sister again? Much like with Lloyd, Mithos sees a chance for this 'Munakata-kun' to be everything he couldn't.]

I'm sure he can do it. [He's not actually sure, but he wants to believe. He wants to grasp onto some scrap of what he used to wholeheartedly believe -- that someone could make a difference. Even if he failed, even if he's a tad envious of the fact that others could succeed when he couldn't, he wants to encourage it.] Just keep believing in him, even as the two of you get your lives together. And be careful -- don't let anything happen to him, and don't let anything happen to you.

[Part of him hates that he feels obligated to tack that last bit on, but he knows what can happen when even the most idealistic of people loses someone close.]
