i think my favorite thing about the admins is how: while it's ambiguous how they exactly got their power, its very clear it corrupts the individual to some extent and turns them into a sort of caricature of themselves over time. yes, power corrupts, but seeing how drastically romeo acts compared to his human form, i do think there could be something going on there.
i'm aware there's some issues with the writing of s2, mainly because they were struggling with bankruptcy at the time, but man... man its crazy...
like xara, prior to the admin stuff, could have been a really nice person who had a hard time interacting with others and expressing her feelings, frequently getting frustrated at things, but had her friends to help her through it. the admin powers could have caused her over-protectiveness and arrogance to go into overdrive, making her less of a "people person" as she mentioned in chapter 3.
fred is a bit of a hard one; we never hear of him directly, because he isn't alive anymore. whenever we do hear of him, he's told through an idealized memory or through a medium where there's a degree of separation. he's the only admin we don't actually see the human version of, and the only time we meet him "in person" is when romeo transformed into him during the final battle in a modified version of their cabin.
fred strikes me as someone who has a hard time talking about how he truly feels, and he does something because he has to and not because he wants to. and someone who frequently frets abotu how someone sees them. i feel like the fact we only see him through a secondary mouth adds to this. he was so secretive at times, that any information he gave out had to be catalogued by his friends so they wouldn't forget.
due to how tired he sounded when he was recording the message meant for xara, it could have been he knew he was walking into his death; but he also knew that there was no other way this could go, and that of all people, he felt like he had to do it.
like again... its bringing out your worst qualities over time. its turning innocent qualities, like wanting to be with your friends all the time, being a little nervous around others, having a hard time interacting with people without getting frustrated, into very selfish qualities. idk its just interesting
