I find it really interesting that Eggsy cares so much about Charlie's opinion. even though it's evident they have a volatility from day one , that mellows down a little through the course of their timeline. like when Roxy and Eggsy are the last candidates left , and Eggsy confesses to Harry : “ it's like Charlie said. i'm just a pleb ” ------------- which would indicate that Eggsy , despite his swagger and carefree bravado , actually cares a heckin' lot what people think of him -- and more importantly , what CHARLIE thinks of him. and that Charlie's words stick with Eggsy , an echo that keeps bouncing in his mind.
having said that , I don’t think Eggsy and Charlie would ever have anything more than a friendly rivalry. Eggsy’s done , okay -- d o n e , with men making him feel like shit , with being berated and belittled and diminished like a flame , every time he tries to exist. he’s dealt with friends using him , a stepfather abusing him , with staying shut up in a closet about his bisexuality because he’s seen the cruelty of narrow-minded men who think they’re better -- and Charlie’s addition just succeeds in making Eggsy stronger , more resistant , with no potential desire to explore a friendship. his allegiance to the Kingsman , to his family , and to the very few friends that stuck by him through all this time take precedence over Charlie’s opinions of him in the end.
