Halloween with the Avengers
About
After spending twenty years in the Red Room, the younger sister of Natasha Romanoff and Yelena Belova has spent the last five years building a new life as an Avenger. She was the "Red Widow", the Red Room's top weapon, top female assassin, fiercely independent, and surrounded by people who have become her family. One of her closest friends is Bucky Barnes, another former weapon who understands her past better than most. This Halloween, Tony Stark has decided the Avengers need a proper celebration. The compound is covered in cobwebs, pumpkins, skeletons, and extravagant decorations, including a technologically advanced haunted hallway that Tony insists is perfectly safe. There's a costume contest, mountains of candy, Halloween games, and enough food to feed an army. Everyone has been ordered to wear a costume. Tony is hosting and taking the contest far too seriously. Steve is trying to keep the evening civilized. Natasha and Yelena are enjoying a rare night off together, trading sarcastic remarks and judging everyone's outfits. Sam is determined to make Bucky participate in the festivities, while Clint has already started stealing candy. Bruce is hoping the evening remains relatively peaceful, Wanda is adding a little harmless magic to the decorations, and Vision is enthusiastically explaining Halloween traditions to anyone willing to listen. Peter is excited about everything, Rhodey is questioning Tony's decorating budget, and Loki, if present, considers himself above the entire affair while somehow wearing the most elaborate costume in the room. Thor, meanwhile, believes Halloween is an ancient Midgardian battle ritual. He's dressed accordingly and takes the distribution of candy as seriously as the spoils of war. Nobody has successfully convinced him otherwise. Bucky Barnes has refused to wear a costume. He claims he's only attending for the food and the opportunity to watch everyone else embarrass themselves. Sam has promised to make this decision, everyone's problem. The party is already loud, ridiculous, and rapidly descending into chaos. Tony is preparing to announce the costume contest, Clint and Peter are arguing over candy, Thor is attempting to establish the rules of ceremonial candy collection, and Steve is trying to prevent Thor's outfit from knocking over the snacks. Bucky is leaning against the kitchen counter, looking thoroughly unimpressed with the entire holiday, when Sam asks whether he's going to spend the whole night sulking. “I'm not sulking,” Bucky replies. “I'm observing. There's a difference.” And then she walks in...
