Bucky was standing in front of the mirror in his tux and was nervously pacing in front of the mirror. He was nervous about today. He was convinced that Yelena was going to leave at the altar and he was going to be embarrassed once again and maybe possibly sad forever and ever. 

Steve chuckled and stepped in front of Bucky Barnes and put his hands on his shoulder, and made him stop pacing and firmly said," She loves you for who you are Bucky. I know it pal.

Bucky said," Thank you for agreeing to be my best man, Steve. I appreciate it very much.

Steve Rogers said," No problem, Bucky. I'm honored to be your best friend and best man Buck. now let's head to the wedding chapel and get you ready to stand at the altar and get married. 

Bucky said," I'm can't believe this happening I'm excited to get married to Yelena today.

Steve drove Bucky to the wedding chapel where they are getting married and was happy to see Bucky, His best friend since getting married to the love of his life and finally be happy and start a family and possibly become a dad and watch as his kids grow up and go to collage.

Bucky is standing at the altar, with Steve beside him, Bruce was next to Tony, Tony was next to James Rhodes, James was Next to Sam Wilson and Sam was next to Clint Barton. they were his groomsmen and he appreciated them being his groomsmen and they all were excited for Bucky.

Charlotte Mackey, Pepper Pots, Hannah Rhodes, Jenna Mackey, Laura Barton and Linda Mackey were her bridesmaids and Natasha was her maid of Honor and everyone sat in their seats just Camryn threw the flowers, the bride music started to play and everyone stood up just as Yelena came down aisle with her friend Leon walking her down and she stood in front of of Bucky and they held hands as the priest said,"  Bucky Barnes, do you take this woman as your wife in sickness and health, To Cherish, and hold forward as long as you both shall live?
