I think one of the things that frustrates me with the Pit Babe fandom nah it’s the writers really is how incapable some are at understanding Charlie’s motives.
To be crystal clear, this is 99.9999% the writers issue. They are the ones that have left Charlie’s character mostly underwritten and pushed it into the subtext and/or allusions - so I’m not really blaming the fans. It’s a writers problem.
Ironically his power is a great allegory for his character. He is the martyr. He is the one who tries to take everyone else’s problems onto himself. He is self sacrificing to a massive fault.
Because that’s all he’s ever been good at.
All of these characters have some huge traumas from living with Tony. Some are very obvious, like Kenta. Others are far more invisible, like Pete. However, they all have them.
Out of the cast we have who lived with Tony, only Charlie and Kenta were treated with exclusive negativity. Mental and/or physical abuse throughout the majority or entirety of their time with him.
Babe was loved, until he figured out the truth. Pete was mostly oblivious. Way wasn’t treated with as much affection as Babe, but he was trusted and respected well enough for Tony to let him live alone for over a decade. And Jeff, was very much wanted.
Charlie was cast aside. Cast out. He was unwanted because he was useless.
He found value in protecting things he loves - in protecting Jeff and protecting Babe.
And yes, Babe loves him but as the show’s established their communication is awful and Charlie is insecure with their relationship. He might have mentioned it because of Willy, but I think it’s always been there.
Why? Because he gives and gives and gives and it doesn’t always seem like Babe cares the same way.
So all Charlie KNOWS he has, is his ability to give up everything for Jeff and/or Babe’s safety.
It’s flawed as shit. But so are Babe’s actions, Kenta’s mindset, Pete’s willingness to screw anything that resembles Way.
Just because the show depicts other characters’ flaws more overtly and with more nuance, doesn’t mean Charlie’s reasons don’t exist.
