Day 5: Krista
Everyone was bored (other than Levi, who was cleaning), and sitting around in small groups of friends. No one could think of anything interesting to do, plus, since it was almost Christmas time, they wanted an activity that would get them in the Christmas spirit. In fact, the recruits from the 104th squad had a sort of unspoken competition going on, the winner being the first person to come up with a good idea. They even had rules: it couldn't be something obvious like making cookies or decorating the Survey Corps HQ. It had to be a more unique idea, though something that wasn't too far-fetched.
Krista eventually came up with an idea - making holiday themed sweaters. She suggested a contest centered around who could make the most creative sweater. Since it would take time to sew and decorate the sweaters, she suggested that the actual competition be later in the month to give everyone a chance to finish without feeling rushed.
"That's a good idea," Sasha commented.
"I thought you'd refuse to accept any idea that didn't involve food, Potato Girl." snorted Jean.
Sasha glared at him. "Well, you thought wrong."
"Like usual." Eren whispered, though not quietly enough for Jean to miss the statement.
"Hey! What did you just say?" Jean asked angrily.
Sasha smirked, "You heard him, Horseface!"
"Alright, alright, everyone calm down," Armin, ever the voice of reason, spoke up. "Let's vote. All in favor of Krista's idea, raise your hand."
Sasha, Connie, Krista, Ymir, Armin, Eren, and Mikasa rose their hands. Ymir glared at Jean, Bertholdt, and Reiner until they rose their hands as well.
"It's unanimous. Krista's idea wins." Armin stated with an air of finality, before walking off. As the others began to disperse into small groups again, they realized there was probably not much yarn available to sew the sweaters with. Upon that realization, everyone charged towards a supply closet that held spare yarn and other materials. Armin, who had reached in first, claimed some yarn before darting out of the way of the others to avoid being trampled. Ymir reached the closet next, thanks to her agility. She grabbed yarn for herself and Krista before dodging her squadmates, some of whom were attempting to take some of the yarn from her. Once she was out of reach, she headed over to where she had told Krista to wait, safely away from the fighting teens. Sasha was next to retrieve some yarn, due to her past she had no trouble 'hunting' the yarn and avoiding her quarreling squadmates. Mikasa grabbed some yarn for herself and Eren, who was too busy fighting with Jean to pay any attention to the fact there was almost no yarn left. Finally, Bertholdt and Reiner, who hadn't really cared about the contest in the first place, took two of the last three bunches of yarn; Connie got the last one. When Jean and Eren eventually stopped fighting due to exhaustion, they noticed there was no yarn left and promptly began arguing again, this time blaming each other for wasting so much time. Arguing quickly turned into brawling. Eventually, Mikasa dragged Eren away from Jean, seeing that if no one interfered, one or both of them would end up seriously injured.
Jean later found some yarn in another supply closet and soon everyone was (more or less) peacefully sewing sweaters.
That evening in the Mess Hall, Krista announced when the competition would be held and that the judges would be Hanji and Commander Erwin to avoid any favoritism.
