Holy shit, it literally just occurred to me that Aaron’s fake flirting went on so much because he was trying to get rid of Dean so he can escape, but Dean is not just running away like he ‘should’ be doing.
It’s a Star Wars reference and they’re both super big nerds
Charlie is a lesbian and she means she loves him like a brother
Dean has said that she’s like the little sister he never wanted
to a geek, Dean’s reply is 1000x better than a simple “I love you too”. Especially in a situation like this where she was a bit hesitant to say it. Dean broke the tension while also showing how much he appreciates her and the geekdom she brings into his life
