What if a side effect of cryogenic stasis is amnesia due to the lack of activity in the brain? You could do character creation in the cryopod and see your character frost over. You could hear or maybe see the abduction event but you wouldn't know who they were. Parts of player dialogue could be altered to change the finding your son bit to just trying to figure out who you are. Codswirth could be altered to just knowing you and not mentioning wife or kid.
