Girl, You're Amazing

Chapter One

He couldn't fathom it. He couldn't understand how in the name of the good Lord he'd managed fall in...NO! It wasn't falling in love at first sight! It wasn't like that at all, no! He refused to even accept that as an option. He felt a tiny hand on his knee and looked down to see his niece, Claire looking up at him with her big beautiful eyes.

"Uncle Cassie?" She asked, tugging his jeans nervously.

"Yes, Claire?" Castiel replied, getting off the chair and kneeling down in front of the almost three year old.

"Can…can I has an appie?" She asked, Castiel beaming in response and picking her up to give her a hug, "Pwease…?"

"Sure." Castiel replied, grinning as she hugged him a little closer, "You sure like your apples, huh?"

He received a nod in response and a little chuckle from Claire.

"Your mommy and daddy will be home soon, sweetheart."

"Will they?" She asked, "That's goodie, 'cause I miss them today."

"Really?" Castiel replied, "Well, it's alright because they'll be here in a half hour. Not long now."

"Okay." Claire said sweetly, kissing her uncle's lightly stubbled cheek as he popped her on the floor.

She toddled away eating her apple and Castiel followed her, sitting her on his knee as she coloured a picture against the coffee table.

As promised, Amelia came home a half hour later and she smiled as she saw Castiel sat with Claire. She knew it wasn't Jimmy, simply because Castiel's eyes were bigger and brighter, and his voice was deeper than Jimmy's. Also he looked that little bit more serious.

"MOMMA!" Claire cried, scrambling off of Castiel's knee and running towards her mother, Amelia smiling and sweeping her baby into her arms.

"Hey, sweetheart!" She replied, kissing Claire's cheek, "How was your day?"

"Gweat!" Claire squeaked, "Uncle Cassie and I coloured piccies!"

"Wow, I'll look at those in a second!" Amelia said, kissing her child's forehead and popping her on the floor, "Hey, Cas."

Castiel stood up, legs a little achy from Claire being sat there for thirty minutes and hugged his sister-in-law.

"Hey, Amelia. How was your day?" He asked sweetly.

"Wonderful thanks," Amelia replied, "What about yours? Has Claire been good?"

"An angel as always." Castiel answered, Amelia smiling and nodding, turning as Jimmy entered the house.

"Hey." He said quietly, taking off his god-awful trenchcoat and hanging it on the coat hooks in the hallway.

"DADDY!" Claire sprinted on her tiny legs and Jimmy scooped her up, pressing kisses to her face before she snuggled him.

"Hey, baby." He said softly, "Have you had fun today?"

Claire nodded and rested against Jimmy's shoulder, Jimmy going and hugging Castiel. Somehow, during the hug, Claire had been switched from Jimmy's arms to Castiel's.

"Hiya, Uncle Cassie!" Claire chuckled cheekily, Castiel kissing her head and passing her back as she reached out for her dad.

No-one knew how she could tell them apart so easily, but Claire must've just had that knack.

"Thanks for everything with the whole babysitting stuff, Cas." Jimmy said, "We really appreciate it."

"It's no problem, I love looking after Claire." Castiel replied, "I'll see you soon, Claire."

"Bye byes!" She said sweetly, kissing his cheek and petting his hair.

"Bye, everyone." He said softly, grabbing his jacket and waving as he left.

All the way home he couldn't forget about those beautiful brown eyes, the stunningly straight nose with a pointed tip, those full lips, that chest-length, curly dark brown hair, that beautifully shaped body…

Snap out of it, Castiel.

He realised as he approached the front door. He'd fallen in love…at first sight.
