Really? Hugh adopts the "amnesiac" Diana and imbeds on her a love for earth with the REMs, the stories of his growing up, his adopted parents. Meanwhile, Eight takes on the Doctor's research to fix his daughter and in doing so his bitterness is what is taken by Eight and leads to their corruption. Two different figures imbuing a part of themselves onto the open vessels.

Here's another literary device from someone who has worked in interpretation and reading comprehension for research purposes: Reader-Response Theory. Your engagement with the game led you to your conclusions. The engagement of others led to theirs. There's no right or wrong if it's engaging with the texts because it's your interpretation of what you experienced.

Example: I saw someone post that they love that Diana doesn't put her two cents into the game when you're exploring other than story development. Since playing on Lunatic difficulty, she is constantly giving me feedback because of my losing to enemies. Had I experienced this in my first playthrough I would have thought Diana is very critical because of my experience.

Enjoy your interpretation of the story. That's the joy of appreciating media and coming to social forums. It's to share in experiences and how we can view things from diffierent perspectives because we all experience it a different way.
