John had done so much and lost so much, so it's not a surprise when John finally admits that he's just tired. It took a lot for him to finally admit he was tired, but relaxing didn't come easy.
Every little noise that was made, he'd snap up and grip his gun like it was a life line. Every time the dog jumped up on him, he'd worry that something wasn't okay when really the dog just wanted to go outside. His mind was constantly on work on the paranoia that something bad was going to happen to him. That's why when someone knocked on his door, he would only walk towards it with a gun in his hand.
He slowly approached the door with the gun hidden behind the door and he opens it only to reveal you. The minute he saw you, he set his gun on a table and took you in his arms, hugging you tightly. You were the only person he let himself be vulnerable with and be so soft and gentle with.
After a few minutes, neither you or him spoke as you sat cuddled together on the couch, but the minute he heard something outside, he jolted up and held up his gun with you against his chest in a tight, protective hold. You could feel how tense he was and how much he needed to relax.
