The idea didn’t occur to Dean until he saw a pair of girls walking by in the field that he and Sam had chosen to stop at in order to sit on the hood of the Impala and enjoy the food they’d picked up at the nearest drive through. He left Sam sitting on the hood, looking confused as he packed up their trash and tossed it in a nearby garbage can as the girls walked back over to the car with Dean.
“What’s this?” Sam asked as Dean handed one of the girls his phone. Dean recognized the ‘are you seriously picking up a chick now’ look that Sam favored him with.
“Do you want the car in the picture?” one of the girls asked.
“Yeah, that’d be great, thanks,” Dean responded as he pushed Sam into place next to the Impala and then stood next to his stupidly tall little brother, hands in his pockets. When Sam realized what was happening his arm went around Dean’s shoulders.
The girl counted off to three and then Dean heard the click from his phone as she took the picture, smiling at the screen and looking pleased with the image. “Here you go.”
“Thanks.” Dean took the phone back but didn’t bother looking at the picture as he shoved the phone back in his pocket. The girls nodded and walked off again and Dean could almost hear them giggling and the whispered ‘what a cute couple!’ as they left.
When Dean turned to get back in the car Sam was staring at him. “Seriously?”
“C’mon, still got a few hours driving before we get back,” was the only answer Dean gave him as he climbed back into the car, waiting for Sam to get in next to him before driving off again.
It was a few days before Dean was able to take his phone to one of those pharmacies that had a way to print out digital pictures. He got a few looks for only wanting the one picture printed out but he wandered the aisles until the picture was done. He then drove back to the batcave and went straight to his room. The picture went on his desk right next to the picture of him and Mary that he’d left there and he smiled a little.
“Wish you could see Sammy now, Mom,” he said quietly.
It wasn’t like Dean was going to start collecting pictures but he liked having a place where he could safely keep two normal pictures of two of the most important people in his life and that was all he cared about.
