Three months later

"Just call Cas," Dean snapped at her, taking another swig of his beer, "He's not answering to us."
"Then he's busy," she said softly, her eyes scanning the pages in front of her as Alice In Wonderland pulled her back in to its dreaming world. Her dream however was cut short when Dean threw a crumpled piece of paper her way, just skimming the top of her head. She dragged her eyes away from the book and glared at him. "Dean seriously. He doesn't come when I call all the time, hell if he did he'd be here more often than he is now. I haven't seen him in two weeks either." Before bowing her head and returning to Lewis Carroll's world. She was once again interrupted by Dean, but this time he was standing beside her chair and was handing her a beer.
"I've been meaning to ask Will. You and Cas, how are you?" he asked hesitantly, refusing to meet her eyes.
"Really Dean," she snorted, marking the page she was on and placing the well read book down on the table, "We're going to talk about feelings?"
"It was just a question," he mumbled and walked back to his chair on the other side of the room, slouching down with his eyes shut.
"We're okay," Willow spoke up quietly, "I mean I miss him, and I worry. But I know he does too, and he comes when he can. That's important. We just have to... tread carefully."
"Woah," Dean sat up, his eyes wide staring at her, "you mean you two haven't..." he trailed off.
"The angels," she sighed frustrated, "there isn't supposed to be a me and Cas, we have to make sure he's safe first for his sake."

"Good 'cause his was going to lead to the birds and the bees talk," he raised his eyebrows, the relief evident in his voice.
"Dean... really," she laughed, pulling her hair out of her pony tail and picking Alice in Wonderland, settling back in her chair, "I mean, I'm not exactly a virgin."
"What?" Dean said all but jumping out of his chair, at the same time Sam walked in carrying a bag full of takeout food.
"You get her to ask Cas yet?" Sam asked Dean, handing him pie and coffee, before handing Willows crumpets to her, "you still read that?" he asked, raising his eyebrows as he noticed the tatty cover, "I thought Dad threw it out ages ago."
"Please," she smirked under her breath, "I'm never going to lose this book," as she placed it down gingerly looking back up at Sam, "and I'm not going to call Cas, if he's not answering you then he's busy."
"But he gave you that if you ever need him," he nodded towards the circular ornate pendant hanging around her neck.
"No," she corrected him, "he gave me this for when I'm in danger. Not when we get stuck."
As she spoke Willows hand automatically dropped to the silver ornate pendant hanging around her neck, as she stroked the cold silver she remembered the day he gave it to her.

Flashback

I was busy picking my clothes out of the wardrobe, after spending so much time with Bobby's at one place I had picked up a large collection of clothes, too large to take on the road, the most heartbreaking process was deciding what I had to leave behind. I was mid way through chucking some already packed clothes out of the back to make room for some other clothes when Castiel appeared.
"You appear to be having fun," he almost smiled as I caught him watching me out of the corner of my eye, "that was sarcasm," he added, breaking out into a fully fledged smile.
"You're learning fast," I smiled at him, crossing the rooms as I laid my head on his chest, feeling his arms around me and his lips on my forehead, until we hurriedly pulled apart as I remembered how much danger even that simple gesture was putting him in.
He walked over to the bag on my bed and pulled out one of the many books I'd shoved in there, he looked at me questionably as he held up Alice In Zombie land, I shrugged and grinned, "It's good not as good as the original granted."
"Why are you bringing to many books?"
"I like books," I smiled and looked into his eyes, and the way that they'd changed since I'd met him a month ago. They were still the most beautiful shade of blue I'd ever seen but instead of them being cold and emotionless, they looked happy.
"I have to leave," he said sadly, ducking his head as he pulled something out of his trench coat, he silently handed it to me and kissed my cheek. He sighed as he pulled back, "I don't want you hunting, and you know that already. But I respect that it's what you want to do, just... Never take this off. I'll want to know you're safe." And with that he was gone and my room was empty.
I glanced down at the necklace in my hand and I felt my face slip into a girly grin. It was easily the most beautiful thing I'd ever seen. I circular pendant on a leather strap which hung to about the middle of my torso and as I looked at it closer I saw that engraved very finely on it was the Cherry Blossom tree that was in your dream. I pealed the note open and my chin nearly hit the floor, once I'd read what it said.
'Willow, in this pendant is a feather off my wings sealed inside, so I can always be sure that you are out of harm's way. Please be safe, I'll see you as soon as I can. Castiel."
(End flashback)

"You called?" Castiel said quietly as he appeared behind Willow, making her jump, his voice sounding so cold it made the hair on the back of her neck stand up.
She was aware of the blush spreading across her cheeks as she stood up nervously, the blush on her cheeks getting brighter when she felt Dean and Sam's eyes on her.
"Oh no," she mumbled, ducking her head down as she took a step towards him, "I was just uh – thinking."
"Good, because I can't help," he said emotionlessly, dropping a crumpled piece of paper onto the floor, his eyes boring into Willows. She gave him a slight nod and smiled softly just before he vanished.
"What the hell was that?" Dean exclaimed as she picked up his beer and began to pace, but Willow was already panicking. She dropped to the floor and flattened out the piece of paper Castiel left and growled quietly under her breath, she threw the note at Dean before swooping up the car keys and rushing out, taking the stairs a two at a time.
"Will," she heard Sam and Dean simultaneously yell after her, she dived into the car and put the keys in the engine, tapping her fingers on the steering wheel impatiently, her fingers shaking as the boys jumped into the car behind her.
"Will what's going on?" Sam asked, leaning forwards on the seat as Willow had to blink the tears out of her eyes as they sped down the motorway.
"I don't know," she snarled through grit teeth, "under the seat pull out the blades we'll be there in a minute."
Sam and Dean silently did as she said, silence hung in the air as Sam and Dean just exchanged terse glances with each other as they pulled into the deserted factory, Willow leaped out the car and snatched the silver angel blade from Sams lose grasp as she ran into the factory, kicking the discarded door down, she could hear Sam and Deans footsteps behind her and them yelling her to wait, and deep down she knew she should. The fact Castiel had made them sneak out was saying something, there was something going on and it could be anything or anyone but Willow just couldn't stop, the idea of something happening to him only made her run faster.
"Castiel," she cried as she noticed his body lying on a pile of debris, she glanced up at the blood drawn angel sign on the wall above him and made a mental note to ask him what it was, but her mind was drawn back to his unconscious body.
"Castiel," she shook him, "wake up."
She heard Sam and Dean appear behind her, they hesitantly stood behind her, as she shook him. "Cas stop it," she snapped at him, shaking him more viciously, which was when he jerked awake. Willow broke into a grin, and pulled his head into his arms, "you ass, never scare me like that -"
She didn't get to finish her sentence because he pushed her away, with all his strength, pushing her onto her bum as she flew backwards. He jumped to her feet and looked at them, confusion etched onto his features.
"Cas, take it easy," Dean spoke up.
"Oh, no," he said, looking around, looking more confused by the second.
"Cas, you okay?" Sam asked him, looking at Dean with raised eyebrows.
"Urgh, Castiel. I'm not Castiel. It's me," he said and Willow slowly pulled herself up to her feet and really looked at him. He was different, he no longer carried himself in that awkward way he usually did and his voice wasn't husky, it sounded light. Carefree and normal.
Willow took a deep breath in and spoke up, surprised at how shaky and meek her voice sounded, "You're not Cas are you. You're Jimmy."
"Yes, I'm Jimmy."
"Well where the hell is Cas?" she snapped, anger taking over her body, replacing all the despair and fear.
"He's gone," Jimmy said plainly, smiling at Dean and Sam, but refusing to meet Willows eyes, none of them were.
"No," she whispered, turning around and went to punch the wall instead of punching Jimmy's smug face for letting him go, but the anger disappeared as suddenly as it appeared and instead there was just a numb feeling left in its wake.
