[The cant of his head and the quirk of his brow says plainly enough oh yes, it's definitely possible.] Moment of death, moment before, moment after--it's not like we've got some multiversal doctor doing an exam on everyone the moment they're taken. [And if someone had been dead for even longer, with no memory or sense of passing time, how would they know here?]

What we do got is folks on this side who know they've died. They know how, they've got memory of it happening, and they've got people from their worlds here who confirm it sometimes.

I could spin you half a dozen theories on how that happens, but it does happen. It's this or nothing for some folks here, and they know it. [So there may be more ways in one in which people here don't have much else but each other.]
