Sure. Going off the data, so far whenever someone dies and is replaced by a second version, the first version hasn't come back even if the second dies. Don't know if that means anything, but it struck me as interesting. We don't even know if we're even really talking about two versions of the same person, or one person who's lost their memories. People gainmemories while they're dead sometimes; there's nothing to say they couldn't lose them as well.
