"Sibby, come over here." Dean didn't take his eyes of Barachiel, his teeth grinding down and hands tensing.

"Dean, are you okay?"

"I'm fine, Sib. Just come over here." He held out his hand to her, giving her a stern look. "I gotta talk to you. Alone."

".. Alright." Sib hesitated, and slowly she let go of Barachiel's hand to take a few steps towards Dean. He grabbed her as soon as he could, pulling her into the hallway by her arm like a child that did something wrong.

Sib's eyes were everywhere but where they needed to be and he knew whatever that thing was had done something to her. She seemed like a little child being pulled along by whoever took her hand. Dean held her by the face to stop her eyes from wandering about- he had to practically shake her to get her to look at him. When she finally did, she looked horrified. Something about how he was going about this made him feel wrong. He didn't like touching her like that.

"Listen to me." Dean whispered loudly, throat hoarse and words cracking. He might as well have screamed it. He had gotten her attention but she was looking at him like he was a monster. "Sib, listen; that's not Sam."

Sib's mouth dropped slightly and she went to look into the room only to have her face pulled back towards Dean. That's when she noticed how puffy his eyes were, how his mouth moved even when no words were coming out. He looked absolutely drained. "I don't understand-"

"Sib, Sam's dead." With everything going on, he didn't realize how it sounded until her body started trembling. He could've been nicer about it, could've said it differently.

"No!" She shouted, trying to push him away. It was a completely unreal idea to her. She wouldn't hear it.

"Sib you gotta believe us. Cas told me everything- how he tried to save you, how this.. this thing jumped into Sam when he was dying."

"What thing? I don't understand."

"Look Sib, I'll explain but right now I gotta go in there and handle this. Can you trust me?"

"Dean-" She pleaded.

"Can you trust me?" He repeated, this time louder. His eyes were wide and he looked like some crazy person to her. Honestly though, Sib couldn't recall a time that Dean was wrong about something. She didn't have a choice but to believe him but she still hoped he was wrong.

"Yes."

"Then stay here with Cas and let me figure out what the hell is going on."

She nodded in his grasp, turning her head to the footsteps to find Cas with his head down- waiting patiently to speak with Dean. Without another word he let her go, storming past Cas, not allowing him to say a word. Sib was about to fall apart and somehow the angel had seemed to sense it.

"Cassidy, come here."

Sib walked slowly, approaching him like she was afraid that he'd hurt her. Cas stepped in front of her, looking up finally. She had never seen him so distraught. "Close your eyes."

Sib listened, feeling his thumb press to her forehead. A whirlwind of pain and memories flashed past her eyelids, everything from Elysium's taunting to the dagger she put through his heart. She saw Sam lifeless on her lap and a pain shot into her chest like she'd been stabbed again. Sib gripped her chest tightly, choking on the pictures that flashed. She saw Castiel, how he'd cared for her and brought her back, how he'd restrained what was no longer Sam to keep him from harming anyone. She saw how he lied to Dean to keep her from feeling his wrath, how mean she was when she woke up and how Barachiel had made her forget all of it so she wouldn't hurt for just a little while longer.

By the time she was done, her feet had given out and she was on the floor gripping her head and grinding her teeth together. Cas stayed crouched beside her, holding her up to keep her from falling on her face. He kept saying how sorry he was but it didn't stop the convulsing, didn't fix the whole in her chest, didn't bring Sam back. Everything felt so hopeless.

"Cassidy, you have to get up. You're going to reopen your wound."

Sib didn't care. Part of her wanted to die and the other half already did. "We have to fix this. We can't just-"

The noise that left her mouth made Cas jump. Obviously he'd spoken too late because she was losing breath and shaking. He leaned her back against his knee and pressed his hand to her chest- feeling the blood begin to seep through. She had tried to say something but it only came out garbled. "Don't talk, you're making it worse. Let me fix it."

They heard the banging in her room and Sib tried to move but couldn't. Cas looked up for only a second before looking back down at her. "Don't worry about that."

Castiel's lips were moving still but she could barely hear him, everything was slow and off track.

"Cas." She tried again, using her shaking hand to hoist herself up a little. He pushed her back down to rest on his lap as gently as he could. She'd think the stern look he gave her impossible, his eyes were always so gentle. "Cas."

"I said don't worry about it. I'm worried about you right now."

"I don't care about me, go get Dean."

"Cassidy-"

She cut him off, pulling him down by his coat. "Go get Dean. Now. I'll be fine."

"No." He jerked to free himself from her grasp, nearly glaring at her. "I'm not going to leave you. I'm going to fix you."

Sib slammed her head back down against it's cushion, closing her eyes tightly when she felt the pull on her shirt. The fabric was stuck to the hole in her chest and he was pulling and ripping skin. She hissed and gripped onto him to keep from passing out. "Please go. I wanna see Dean."

"You'll see him when you're better."

"Cas," she spoke with heavy breathing over the sound of fabric ripping. The air hitting the fresh blood made her shiver and kick her foot against the floor. "You're going to kill yourself. I saw what happened-"

"I'll be fine." Cas tugged the halfway ripped shirt down her arm and eyed her. "Can you stay still?"

She gave him a strange look, she hadn't realized she was fidgeting. She dropped her arm and gave a single nod. He looked awkward for a moment, going for the bloodied patch of skin before rearing his hand back. "Can you.. do something about that?"

Sib tipped her head down slightly to see what the commotion was about and sighed. "Really." And with that she lifted the left cup of her bra to un-stick it from her skin, folding it slightly so he could see the cut better. "What did you do when I was knocked out earlier?"

"I had Dean do it."

Sib rolled her eyes despite her pain. "The innocence of you is almost disturbing."

"Hush." Cas muttered under his breath, leaning over her a little and pressing his hand down on the spot. She immediately grimaced. It burned. She knocked her feet on the floor and tried to grip at anything to keep from moving her torso- the hand that wasn't death-gripping Cas sliding on the ground like a fish out of water.

"Fucking shit!" Sib hissed and slammed her head against his leg, closing her eyes tightly.

"I'm not even doing anything yet!" He whispered back loudly.

"The hell you're not!" And then it dawned on Sib. Her eyes came flashing open to stare at him. "Wait, is this gonna hurt?"

"A little bit. It'll hurt less if you don't move." He sighed, pushing the hair from her face so he could look her in the eye. "If you start feeling tired you tell me, Cassidy."

That didn't sound good at all. She swallowed. "Yeah, okay." Why was she breathing so heavy? She didn't remember that pinching tightness in her chest a moment ago. Cas closed his eyes and for a moment there was peace. Maybe it was from seeing him calm down.

Then there was an unbearably strong pain in her chest that hit like a flash of lightening- burning her from the inside out and making her cry out. Cas pressed his hand closer to keep her down and still the shaking, his face absolutely pale from the sound. Her vision was fogging quickly and her head was swaying, her nails grinding into the ground. The agony seemed to last forever.

He stopped only when her eyes rolled back, allowing her to catch her breath and gently shaking her to keep her awake. "Cassidy, you alright?"

"No." Sib practically hissed.

"What the hell is going on?" She could hear Dean over the ringing of her ears. She turned her head up slightly, watching him kneel beside her. "What's going on?"

"She reopened her wound."

"Shit," he hissed to himself, bringing his hand to his mouth. "You alright?"

"No." Sib spoke again, trying to focus on the face in front of her. "I'm telling you, Cas." She hoped to God he knew what she meant.

"Alright, hold on." He looked towards Dean, holding her up. "Can you keep your eye on her for a minute?"

"What do I need to do?" Dean pulled her over to him as Cas let go, resting her halfway onto his lap.

Cas was already halfway gone down the hall before he answered. "Keep her awake."
