Angel was taking down a vampire when she spotted the creepy, Death look-alike. She paused in her actions, her emerald eyes narrowing in on the creepy guy.
"Angel! Watch out!" Dean called out.
The huntress ducked just as Dean swung his machete with a grunt, cutting off the head of the vampire that was sneaking up behind her.
Dean lowered the machete, then looked at his twin, "what the hell? What were you looking at?" he asked her.
Angel pointed towards the guy behind Dean, "him" she answered.
The hunter turned around, stepping back when he saw the creepy Death-guy, "who the hell are you?" he demanded.
The man lifted his palm and a mark began to glow, "Angel Winchester! Night has chosen thee! Thy death will be thy birth! Night calls to thee; harken to Her sweet voice. Your destiny awaits you at the House of Night."
Angel glanced at her twin, before looking back at the guy. Everything happened so fast that it took her a while to register the pain she felt as she crumpled to the floor.
"Hey, asshole, what was that for?" Dean snapped, kneeling beside his sister, placing his hand on her arm.
The hooded Death guy remained silent and instead, left.
Dean huffed, then turned back to his sister and reached out, brushing her hair out of her face, revealing a sapphire blue crescent moon outline on her forehead. "What the hell?" Dean muttered. That thing clearly wasn't there a few seconds ago. As the hunter puzzled over the moon on his sister's forehead, she slowly began to stir.
She moved a bit, a soft groan escaping her lips, her hand going to her forehead. She brushed her fingers over the tender spot where the mark was and winced as pain spread around her eyes. "Ah, shit" she cursed, then blinked, looking up at her brother. "What the hell just happened?" she asked him.
He shrugged, "some dude did something to you. I'm not sure, but after he said whatever he said, you passed out and got this weird moon thingy" he explained.
"Ugh, probably some witch" she said, then moved to sit up, a wave of vertigo and nausea washing over her. She held her hand to her head, groaning softly, "damn, this is gonna be a pain in my ass" she complained.
Dean rose to his feet, then reached out and helped his sister. "Come on, let's get back to the bunker, maybe Sammy can-" he stopped mid-sentence. The twins glanced at each other, both knowing that it won't happen; Sam won't help them, simply because Sam was no longer there, and hasn't been for a good while. They both sighed, then left the barn and headed for the Impala.
Dean drove back towards the bunker, glancing over at his sister every so often, making sure she didn't pass out on him again. Once they got to the bunker, Dean wasted no time pulling his sister inside, laying her on the couch before leaving to grab painkillers and a bottle of whiskey. He came back, then handed everything to his sister.
Angel sat up, taking two pills before chasing them down with a large swig of whiskey, wincing at the burn, but she was used to it. She handed the bottle back to Dean, then laid back on the couch, "what are we gonna do, Dean?" she asked him as he went into the kitchen.
"I'm not sure, our loyal geek-boy isn't here to help us figure it out" he said, coming back with an ice pack, handing it to her.
She took it, placing it on her forehead, hissing a bit as the cold began to sting as the ice pack rested on her moon mark. "Do you think Cas would know?"
"I don't know, Ang. He hasn't answered us in weeks." he said, sitting at the table, watching his sister.
"Ugh, dammit." she complained, closing her eyes.
"She has to leave to the House of Night" a voice suddenly said.
The twins jumped, looking up to see Castiel standing at the couch Angel was on.
"What the hell, Cas? Now you decide to pop up?" Angel asked.
"I have been busy" he simply answered.
Angel rolled her eyes as Dean spoke, "wait, whataya mean she has to leave to the House of Night? What the hell's a House of Night?"
"It's a school for people like her. She has been Marked as one of their own, so she now has to attend their school" Castiel explained.
"How do you know so much about this?" The huntress asked.
"I do not know, i have just heard of it from one of the angel's charges" He answered her.
"Where is this House of Night?" Dean asked.
"The closest one is in Tulsa, Oklahoma" Castiel answered.
Dean snorted, "oh yeah, that's close" he muttered sarcastically.
"Dean, you have to take her immediately, she needs to be around adult Vampyres" Castiel urged.
"why?" The twins chimed together.
"Because she is a fledgling, she has to be with adults in order to survive. A fledgling cannot survive on their own, otherwise, her body will reject the Change and she will die"
"What?!" They both exclaimed, two pairs of emerald eyes wide with shock and fear.
Angel glanced at her brother, who shared an equal amount of panic.
"Yes, you have to take her now" Castiel said.
The twins shared another glance before Angel sighed, "you said it's in Tulsa, right?" she said, clearly defeated. She didn't want to go, but she also didn't want to die.
Castiel nodded, "yes" he said. "I suggest you leave now" he said.
She nodded, "okay" she responded, then slowly sat up, groaning at the pain that pounded in her skull. She held her hand to her head, sighing.
Dean got up and went to help her up, supporting her with his arm around her back.
Angel leaned on him, then walked with him to the Impala, careful not to walk too fast.
Castiel followed them, watching to make sure Angel didn't collapse on them.
Dean helped her into the passenger seat of the Impala, then got into the driver's seat while Castiel climbed into the backseat.
"So, you know where it's at, Cas?" Dean asked as the engine started, the beautiful purr of his Baby's motor relaxing him.
"Yes, I will direct you to it" the angel responded.
The huntress in the passenger seat wasn't listening, instead, she was looking in the mirror of the visor, checking out the mark on her forehead...

Castiel directed Dean to the House of Night while Angel slept in the passenger seat, covered by Dean's leather jacket. Dean kept shooting worried glances towards his sister, but knew she was fine by the way she slept. Emerald eyes kept falling on the mark, confusion and worry etched into his brows. Why did this have to happen with his twin? Why did anything have to happen to his family?
