Bucky & OTA
Bucky was a huge fan of weddings. That wasn't really a surprise to anyone considering how much of a romantic he was, or at least he hoped it wasn't much of one. He was thrilled for Pepper and Dwight, and maybe a little proud of the fact that Steve had been the one to give her away. Plus, Kate had been up there to support Pepper, which meant that whatever had happened between them was on the mend.
There was a big part of him that was just glad to see that kind of unabashed happiness for anyone from his world. There was a lot of pain and anguish going around back in their timeline. Even if he wouldn't be able to have anything else, if going home was the end and it'd be for good, Bucky wanted to savor every moment of the time he did have. These people were his family, on the extended side but family all the same.
Bucky headed for the bar to grab another beer and offered a grin to the person standing next to him. "Hell of a party, ain't it?"
