[He recognizes the look on Shiro's face far too well as he speaks. It's why he tries to reassure him that he doubts its recurring, but he doesn't stop the explanation for fear it will just leave more holes.

Plus, he... knows what keeping critical information does to people. He's seen it far too many times both in Crystallis and in the Tower. Which is why, even before he came to wear the bracer on his left arm, he vowed that he would share what he could to those deserving of trust. And since they were going to be sharing the same roof over their heads and he got no bad vibes from him (except maybe from that arm of his, but then... he can't judge it; not with how he spent over a year of his life).

What worries him is that the older man has heard of something like this before.]

In my experience, there's rarely any apparent rhyme or reason for it. [The being back thing, even if he's never seen this world before in his life. Nothing is true, everything is permitted.

The question gets a faint, amused chortle out of him.] You have to ask? [He smirks faintly.] I spent most of my life fixing that mess before, why stop now?

[He's in it for the long haul whether he wants to be or not, so he may as well do this willingly. Even if only for those who can't.]
