No, H's brother died. We've heard about it a lot-- H was broken up about it, and I think our narrator got... annoyed.

[ which is uh. something? it is Something. anyway, to address the rest: ]

If our-- "powers" [ ew. gross. dick has powers. ] pass on when we die, then the idea might be that if we get to less than thirteen of our total group, we'll be in trouble. What we need is to find the source. Whatever it is that's powering the demons and lets them keep popping up like weeds.

[ and. then at escha's last question, he throws a look at junpei before shrugging ]

Right now, I'm assuming it was a different group.
