Charlie didn't say anything, but the second he lifted his barriers Franklin was hearing his thoughts. The surface ones at first, but Franklin then actively searched his mind. Charlie let him see everything - his whole life story, basically. The way he moved from home to home, his father not having much time for him, and the pure and utter resignation Charlie felt for The Way Things Were. Not that he felt upset at them, but he just... accepted that his life would be the way it was and there would be nothing more. It physically pained Franklin to see that, to know those feelings so intimately and he felt them, too.
And the loneliness. It was almost overwhelming. How lonely Charlie felt, how desperate for acceptance he felt. By the time Franklin had seen it all, seen all he could see before he came back out and came up for air, he could feel tears prickling his eyes. "Charlie." He said, softly, before he pulled him in for a kiss, soft and lingering before he pulled back and took another deep breath. "Charlie, you don't - you don't have to believe what I'm telling you, or accept it or anything but, I want you to know this, okay?" He prefaced, before he took Charlie's hands in his and continued.
"I know this is fast. I know it's scary and I'm terrified I'm going to fuck it up, or you're going to think I'm an idiot and leave me but... I love you. And you don't have to love me back, you don't have to say or believe it. I'm not asking for anything but I do love you, and accept you, and if you want me, really want me, I'm here. You don't need to be so lonely, because I'm here. Okay?"
