But when, and how? Some of the files in question are in different languages, computer code, handwritten. I'm not ruling it out, I'm just saying it's unlikely. Do you know anybody who has the power to change that many files in that little time?

And what about the other memories people are losing? Is this a flood, or something different? If we did find ourselves in another dimension, are there other people we're missing who we just haven't noticed yet, or is Adam the only difference? Is the loss of memory because of the change, or are people just sincerely losing their minds? Give me a plausible working theory and I'll run with it, but those are the two I've got right now.
