Tuck couldn't articulate just how much it meant to him what Will was doing now. Instead he sort of nodded quickly, and tried to take another deep breath, which really only halfway worked. "Okay. Okay okay I'm doing. Oh fuck. Oh fuck, I'm about to see him. Oh god. I can do this. Just-" Tuck glanced out the window, making sure Will could see the front door, glad that he could. "Just watch me? If this goes badly, don't- Don't let me just wander off?" He gave Will an apologetic look, and then he bundled out of the car.
His entire body was shaking as he made his way to the door. He was fairly sure he had forgotten how to breathe. Christopher's place was so nice (but not ostentatious) and Tuck hoped so much it meant his son was happy.
He was seconds away.
Don't cry, you goddamn old fool-
He reached out and rang the doorbell, and then he was fairly sure an eternity passed because so many scenarios of how this could crash and burn flashed through his mind, it had to have been at least a few years.
Then the door was pulled open, and Tuck was standing opposite his son, now an adult man. Daniel looked a little perturbed, but the second his eyes fell on Tuck, he froze. "Holy shit-"
"Christopher?" Tuck said, the name half-sticking in his dry throat. He still couldn't breathe, and his blood was rushing in his ears. "I can expl-"
For Daniel, who had known immediately the man at the door was his father because he looked exactly the same, all doubts were dashed when he heard the man utter his birth name in that unmistakable midlands accent. He didn't need to hear any explanations at all, he just pulled Tuck into a rib-crushing hug.
