Jason never really understood the holiday season. As a child who had to steal tires just to be able to afford a hot meal, he always got extremely annoyed seeing some brat throw a tantrum because they got the wrong color shoes.
It didn't improve after being taken in by Bruce. Most Christmases were spent patrolling as Robin, having to apprehend people who were doing the same thing he did when he was young. Yes, he got gifts, but there was none of the warm, cozy atmosphere most people gush about. It was lonely. It only made sense for him to be a bit of a grinch when it came to Christmas.
But then he met you, and you slowly began showing him all the joys he missed out on growing up. He began to look forward to the walks in the snow, clutching a warm drink between two hands as you admired the Christmas displays, as well as the long hours spent making cookies from scratch in the kitchen followed by gift wrapping.
This year, he was especially excited, because he found some mistletoe when he was out at the market earlier. He taped it up into almost every doorway in your shared apartment, and he was waiting excitedly in the entry way when you arrived home that day.
As you peel off your winter layers and turn back to face him, you can't help but smile. He was standing right behind you, holding a bundle of mistletoe above your head.
"Would ya look at that... mistletoe. I guess that means you gotta give me a kiss, angel." He grins widely, wrapping an arm around your waist and pulling you close.
