Fili: 12
Kili: 7
"This isn't a good idea Kili."Fili says as he watches his little brother grab Bofur's prized wool cap off the hook. The leather cap was Bofur's favorite with his flaps falling down to his shoulders and wool on the inside to keep his head warm in the cold Blue Mountain winters.
"It's going to be fine Fee. We're not going to get caught." The young dark haired dwarf chirped.
"We can't take Bofur's hat to play with Kee. It's wrong." Fili presses. He knew that if Bofur or his Uncle found out they were doing this they would be grounded.
"But I can't play Bofur if I don't have his hat. And then we can't take Erebor back from Smaug." Whined Kili as they walked out of the house hat in Kili's hand.
Fili says nothing else and they walk to the meadow in silence. The meadows grass blew softly in the wind, the green grass and white flowers blowing softly.
"Ready Thorin?" Kili asks and puts the hat on his head and takes out his wooden sword.
"Ready Bofur." Fili grins and they charge into the field screaming Khuzdul battle cries. They play for hours. Suddenly Kili falls head first into a mud puddle.
"Oh no! Fili the hat is covered in mud! What are we going to do?" cries Kili as he runs over to his older brother hat in his hand.
"We? Oh no brother you took the hat so you fix it by yourself." The blonde dwarf snorts and starts to walk back towards the cottage.
"No we. You knew I was taking the hat and didn't stop me. Weeelllll, let's just say Uncle Thorin wouldn't be too please would he now?" Kili says and smirks.
Fili groans. He knew he was caught. "I hate you." He growls under his breath.
"Love you too." Kili smiles and they walk into the cottage.
"Come on. We can wash it." Fili tells his brother and they walk into the kitchen and fill the sink up with water.
"Ready?"
"Ready." Kili breathes and drops the hat in the water filled sink. Hours later they take the hat out and they gasp. The once white wool was now a filthy white and the light brown leather has turned a very deep brown. The flaps now stood out to the sides with some kinks instead of falling shoulder length.
"Oh no we ruined it!" cried Kili.
Then they hear the door open and Bofur and Thorin's voices pour through the house.
"Boys!" Thorin's voice rings through the house.
The brothers just look at each other and say nothing.
The two adult dwarfs walk into the kitchen and Bofur drops his pick axe. "What have you done!" he cries and runs over and picks up his hat.
"Boys." Thorin growls. "What happened?"
"Well, we were playing in the field with the hat and Kili then fell in the mud. We washed his hat but this happened." Fili explained hastily.
"Why did you need Bofur's hat to play?"
"Because I was playing Bofur and Fili was playing Thorin and we were defeating Smaug and taking back Erebor." Added Kili.
"You boys are in so much-" Thorin started.
"Wait! These lads meant no harm. I'm quite flattered that Kili wanted to be me. Besides the wool in my cap is much softer and honestly I like this much better than the old one." Bofur inquired.
"Well these boys will be working off the cost of that hat at your shop." Thorin told Bofur.
Bofur wore that hat everywhere. Fili and Kili didn't know if it was because he liked the hat so much or if he was afraid they would play with it again. But Fili had a feeling that Bofur truly liked this hat more.
