I apologise if the title is bland, but I didn't want to spoil anything for people who have not seen the movie yet. Spoilers ahead.
At the end of I am Mother, mother asks Woman "why did she not remember her parents?", and "why she had survived for so long when no one else could?". And states that "Someone must have had a use for her, until now." And thus her survival was clearly planned by Mother. This heavily implies that Woman must be one of the previous iterations of children that mother raised. I'm willing to believe that, honestly. It seems plausible that mother could have dropped Woman into the hands of survivors, who cared for her. The problem with this? How the hell did Woman know anything about the Tonight Show? She claims that she had seen it "a long time ago". Clearly, this could not be possible given the constraints that we have been presented. The only way she could have watched it is if she wasn't a previous iteration. And if she was a previous iteration that had watched it on one of the holopads, then wouldn't she remember being in the bunker with Mother?
Does anyone have an explanation for what I have mentioned? Is this a plot hole in an otherwise great movie?
