You have no idea how much I love the idea that Varian really wants to protect his friends from making the same mistakes.
Imagine at Varian's uncle's house, Hugo feels left out, frustrated by all the feelings he has, I'm not just talking about liking Varian, no, no, no, but also about the feeling of belonging he has on the team, seeing Yong as his little brother, Nuru as his friend, the feeling of guilt for being a double agent.
Frustrated, he takes the diary of Varian's mother, wants to escape with it and put an end to all those Frustrated, he takes the diary of Varian's mother, wants to escape with it and put an end to all those feelings, Back to the normal of working alone and with no one but a mechanical rat, he tries to run away one night but.... Oh, Hugo underestimated Varian, the fandom underestimates Varian, he's smart and he finds out.
Maybe just an excuse for me to put out a song like 'The history has its eyes on you' that is actually a reprise to ready as I'll never be, but without a big villain to face, the melody is quieter, it's just Varian and his past regrets, he is angry with Hugo, yes, after all he is about to steal his mother's diary but he gives Hugo a second chance at redemption, in the song he reveals him to be the alchemist of Corona, an ex-criminal, an ex-Traitor... But why did I mention a Hamilton song?...
'I made every mistake and felt the shame rise in me
And even now I lie awake, knowing history has its eyes on me'
Let's imagine that Varian says something similar to it, as happened with cass.
A way to say Don't be a villain, don't be me, don't make my same mistakes.
