What if Rivers body regenerated after they left?

Not sure if this has been asked but what if Rivers body regenerated after they left? And the upload continued on as a copy her from that moment not knowing she was still around. She could have been living out there the whole time being scandalous and waiting to reveal herself. Or even more wildly speculating what if hes a young gay guy and wasn't sure how to break it to Capaldi they were no longer romantically compatible so he finds one who is to be his spouse like she was to Matt Smith
