[It's a touchy subject, the idea of regaining their memories from that first wedding of theirs. Of course it was such a joyful day in their life, but maybe remembering the utter bliss would make the betrayal that came just weeks later that much worse.

Besides, they still remember their second wedding, to a much more upstanding and caring version of their spouse, one who wouldn't have left their side if given the chance.]

Hm, I suppose you might be grateful to hear that those worlds we've left behind are do not experience time as we do here. From my understanding, time remains frozen while we are here, as those who have returned go right back to the moment they left.
