Summary: AU. A doctor shouldn't fall for a patient, especially one as young as Castiel falls for when she's in his care for cancer. When she goes into remission and she leaves the hospital, he finds her coming back just because of him. Please R&R!

Belle's Cure

-One-

Eighteen year old Belle Milton sat quietly, her mother, Anna by her side, stroking her hand gently. Another dose of chemotherapy had left Belle with no hair again, and the poor girl looked so sad. It seemed she was never going to leave this hospital, and the doctors kept reporting that her condition didn't seem to change either for the worse or the better.

But as Anna tied the new pink and white bandanna around Belle's head, Belle's favourite doctor, her primary carer came into the room and blessed her with his beautiful blue eyes and dazzling smile. Even though Castiel Novak was ten years older than her, Belle had fallen in love with him and everything about him not long after being admitted when she was sixteen. When he was in the room her pain seemed to fade away and she seemed to feel so much braver and stronger, like she could take on the biggest monster in the world and beat it without even breaking a sweat.

"Good morning, Belle." He said softly, sitting by the girl's side as a tear slid down her face, "What's the matter? Are you in more pain?"

Belle shook her head and smiled.

"Just happy to see you, Cas." She replied, watching him look at the bandanna, "Lost my hair again."

Castiel just grimaced and wiped the tear away with his index finger, tapping the end of her nose with it and smiling softly. That beautiful auburn hair...Belle was always so, so sad when it fell out. He hated it when Belle was sad. She needed to remain positive and he had a little bit of good news for her this morning.

"No more tears now, Belle. I want to see that smile of yours." He said, Belle smiling sweetly which made her mother smile.

It was a relief to see Anna smiling, it had to be said.

"Where's your father?" Castiel asked Belle, the young girl giggling, "He gone to buy you something nice?"

"A new iPod." Belle confessed, "Mine broke."

"What colour?" Castiel asked, Belle biting her lip.

"Pink."

"Lovely." Castiel replied, "So, how are you feeling?"

"Okay." Belle said softly, "I feel good, thanks."

"Well you should." Castiel replied, "The test results show that the cancer seems to be retreating...That therapy's doing you some good."

Anna smiled and kissed Belle's cheek, the young girl reaching over and taking Castiel's hand.

"That's wonderful." She breathed, "Thank you."

Castiel smiled and held her hand in return, watching as Anna kissed her other hand and became a little tearful.

"Will you stay a little longer?" Belle asked, "Mom's gotta go make a phone call and I hate being in here on my own..."

"Of course." Castiel smiled, "I'll stay."

"Thank you." Anna whispered, kissing Belle's temple, "I'll be back soon, sweetie. Keep smiling, huh?"

It was hard to though, Belle thought, especially when you're diagnosed with cancer. Her pain wasn't too bad today, and she felt a lot stronger than the day before. Perhaps it really was because Castiel was with her. Maybe it was him who was helping her feel positive and helping her fight the disease away. They were alone now, and Castiel reached into his pocket, pulling out a small box with a bow on top.

"I got you something yesterday." He said softly, "Just saw it in a store on the way home from here and I just knew you'd love it."

Belle smiled sweetly and took the box, reaching out and stroking Castiel's cheek gently. Neither of them minded when the other touched their face or their hand. They were really good friends, and Belle had been on this ward for coming up to two years, and the doctors had never wanted to take the risk of sending her home, but it seemed that she was on the up.

"Thank you..." She said, opening the box and finding a beautiful silver star inside, sapphires dotted around the edges, "Castiel...it's gorgeous..."

A stunning smile graced her pale face, her gorgeous blue eyes twinkling and sparkling with tears. On the star, it simply read: Stay strong.

Smiling through tears of joy, Belle opened her arms, Castiel joining her on the bed and finding himself holding onto her as she cried into his shoulder. He rubbed her back and fought back tears at the sound of her sobs, as always. He hated it when his patients cried and got upset, and he'd do anything he could to comfort them. When Anna returned, she saw the two sharing a hug and waited until they'd broken apart before entering, her husband Zachariah by her side.

"How's my princess?" He asked, Belle beaming and opening her arms again.

"Daddy..." She breathed, Zachariah sitting on the bed and holding her in his arms, "It's good to see you."

Her father pressed a kiss to her head and sat by her side, giving her a gentle nudge before smiling at her softly.

"It's good to see you too, kiddo." He replied, "I've got you a present."

He pulled out a rectangular shaped box, Belle grinning and opening it to find her pink iPod inside it.

"Thanks so much!" She breathed, "Daddy, it's lovely!"

She hugged her father again, Zachariah smiling at Castiel. He was so grateful to Belle's doctor for paying so much care and attention to her over her two years here. Zachariah had made sure Belle was cared for in the best hospital in Lawrence, Kansas.

"How are you, Castiel?" He asked, Castiel nodding in response.

"I'm good thanks." He said softly, "Glad to find that Belle's getting a little better."

"Yeah, we all are." Zachariah replied, smiling at the young man before nodding, "Thank you. For everything you do for her."

Castiel just nodded.

"It's all part of the job." He said, "Besides, she's worth it, aren't you, Belle?"

"So totally worth it." Belle replied with a giggle, taking in her father's sad eyes as he looked at her bandanna covered head.

"Your hair..." He breathed, stroking her head, "God, I miss those gorgeous curls..."

"So do I." Belle whispered, "Don't be sad for me, Daddy..."

Castiel found it so sweet that still, from being very young, Belle called Zachariah 'Daddy'. It was so lovely that the two still shared that same loving bond, if not a stronger one what with Belle being so ill.

Zachariah shed a tear and Belle wiped it away, sitting forwards and kissing her father's cheek.

"Be happy." She whispered, "I'm getting better, y'know."

She smiled and Anna held Zachariah's hand, feeling her lower lip starting to tremble.

"We've gotta get to work, baby." She whispered, leaning forward and pressing her lips to Belle's forehead, "We'll be back tonight, okay?"

"Bye, Mom." Belle replied, "Love you."

"Love you too, sweetie." Anna said softly, watching as Zachariah leaned down and pressed his forehead to Belle's.

"Love you, baby." He whispered, "See you later, okay? You have a good day."

"You too, Daddy." Belle replied, "And remember, you two...stay strong."

Her favourite saying was 'Stay strong' which is why Castiel had it engraved on that star. She said it to everyone, even if the nurses complained a little about home, she told them to stay strong. He thought that her notion kept her going and was helping her through but he had no idea how much of an impact he was having on her health. She felt so amazing around him that she just willed herself to get better, to stay strong in order to be able to see those blue eyes every day and that stunningly gorgeous smile.

She watched her parents leave and looked to her doctor, her smile fading as tears filled her eyes. She hated being left in the hospital by her parents and she always had. Castiel took in her upset state and he rubbed her hand gently.

"Keep smiling, sweetie." He said softly, leaning forward and hugging her once more, "I've got to go and see to Meg Masters this morning. Looks like she's going into remission."

"Good." Belle sniffled, "That's really good."

"Listen, we've got group therapy this afternoon at two-thirty, okay?" Castiel said, "Now, I know you get a little more tired and pained around that time, so Ellen's gonna bring you in the wheelchair, alright?"

Belle nodded and squeezed Castiel's hand.

"Thanks for the star, Cas." She said sweetly, Castiel smiling in response.

"No problem." He replied, stroking her face just the once before standing up, "See you in a little while, okay? If I don't see you before midday, I'll come and have lunch with you."

"Alright." Belle smiled, "See you, Cas."

"See you, Belle." Castiel said, winking at her which she returned before heading towards Meg Master's room, stopping for a minute to pray that Belle would continue to get better.

Belle sighed and looked across the room, smiling as she saw a familiar face.

"Good morning, Father Novak. I didn't see you there." She said with a grin, watching Castiel's older brother Michael approach her before he sat in the chair by her bed, "How are you today?"

"I'm alright, thank you, Belle." He said softly, "How are you this morning?"

"Achy, but Cas says I'm getting better." She said, "I just gotta keep positive is all."

"That's wonderful." Michael replied, watching as Belle pulled out a bible from under her pillows.

"I've been praying too, see?" She said, putting the bible back.

"I like your new bandanna." Michael said softly, "It's a pretty colour."

"Thank you." Belle said with a smile, "My mother gave it to me this morning."

"How are your parents?" Michael asked, Belle grinning in response.

"Staying strong."

Michael smiled and kissed Belle's forehead, stroking her face gently before patting her hand.

"I must go. I'll be praying for you, Belle." He said, "Keep positive, and keep praying, and I hope you continue to get better."

"So do I." Belle replied, "Goodbye, Father Novak."

"Goodbye, Belle."

With that, the priest left, Belle spending some time thinking about what to say in therapy that afternoon. She took out her notepad and began to write, knowing that if she had something prepared, it would make things a lot easier.
