"Hello, Leah. " Lilith smirked as she observed the small rescue group.

She had to admit though; the odds did not really look in her favor. Three nephilims, two hunters and an angel. However, she had at least thirty demons at her command here.

"I hope you're not expecting me to act surprised. We knew this was a trap." Leah said, crossing her arms at her chest, indifferent look on her face.

"No, I'm not. Not really. Though I have to admit I did not expect halo soldier here." Lilith glanced at Castiel.

"I thought you bible camp soldiers have orders to kill nephilims on sight." She said.

"The situation demanded certain compromise." Castiel replied in his usual tone which made Dean chuckle a bit.

"Oh my God, like talking to a computer." Lilith muttered making Castiel stare at her.

To Dean and Sam, he seemed pissed off whether it was about remark he talks like a computer or the fact she mentioned God. Dean went for the latter one. The small whimper from unconscious Ena made them all snap to the problem.

"So, you just thought you're gonna come in here and walk out with her?" Lilith nodded to Ena who hung limply in hands of Ruby and Sam.

"No, I was looking forward to smite down some demons, I just didn't think you'd actually show up." Leah replied.

"Oh, I wouldn't miss draining you dry for anything, Leah. After all, it's your blood we need to break this seal. This one is good as five others." Lilith said.

"You're not getting it, whore." Ruby muttered.

"We'll see about that. Because I count six of you and I have thirty demons in here. How many can you smite down before we get you?" Lilith smirked.

"Lots, considering that right now, if my senses still work properly in this disgusting presence of yours, there are only ten of them left." Leah smiled and Lilith's face turned angry when it turned to be right.

"What's the matter bitch? Didn't count Cass coming here with his angel buddies?" Dean asked.

"You bitch!" Lilith shrieked and went right for Leah while the room suddenly got flooded by remaining demons, attacking others.

"Leah!" Alana called out.

"I'll take care of her just get your asses out of here!" Leah shouted over the noise demons created.

"That's not a smart idea!" Dean cut in.

"Best one we have right now. So for once Dean, obey me." She replied in really commanding tone, one he never heard before.

It made him inwardly flinch a bit but also made him understand why she was chosen to be leader of nephilims. She may look young and cute but the truth is, she was dangerous when endangered. Hesitantly, he allowed Alana to zap him out while Ruby did the same with Ena and Sam. Only Castiel remained fighting the rapidly diminishing number of demons. While he dispatched demon by demon, Leah and Lilith had their own knife fight. Both of them managed to make a cut on the other and few minutes later, Leah felt weak. Narrowing her eyes on the knife, she noticed very thin layer of semi-liquid substance on the knife. Most likely, demon blood.

"Feeling little dizzy, are we?" Lilith sneered as Leah swayed a bit.

"I can still kill you bitch." Leah muttered and to prove the point, made a long cut along Lilith's arm, making the demon shriek in pain.

Castiel dispatched last of the demons and looked to the other end of the room, seeing two women fight each other mercilessly. For the first time, since he has seen any nephilim, he saw the grace leaking out. Of course, this was visible to angels only and nephilims; demons and humans could not see it. It wasn't a grave wound but he could see the grace that was oozing slowly turn to darker shades, indicating poison. Though he would never admit it to anyone, one of rare things angels could be injured from, was concentrated demon blood. However wrong it was as he was not allowed to feel, he had to admire Leah's stubbornness to take on Lilith even though she was wounded.

"You really are a piece of work. Terin gave your precious little Ena just a drop of it and she passed out like she drank barrels of alcohol." Lilith said.

"I'm not anyone." Leah said.

"You got that right, darling." Lilith waved with her knife before Leah face but missed the target. "The seal would not crack with anyone else's blood." She added.

Castiel was confused at what to do. Leah was clearly getting weaker but this was an opportunity his brethren waited for. For a clue where to look for 'traitors' among their own ranks. A name.

"What do you mean?" he asked, making two fighters look at him.

"Oh, I forgot you are here, halo boy." Lilith smiled. "I'm very certain you guys are still on square one with finding the so called 'traitors' who mated with humans. Am I right?" she asked and Castiel's silence was good enough for her.

"Do you know what it takes for this seal to be broken?" she asked him whilst keeping an eye on the nephilim leader who was clearly starting to lose concentration.

"The blood of a nephilim." Castiel replied, unsure of where this was going.

"Not just any nephilim." Lilith said. "Her blood." She pointed to Leah. "See, it's not about the fact she is their leader. That's unimportant. What's important is the fact that she carries hot archangel blood. The seal demands the blood of archangel though its source can be an archangel himself or its proxy, meaning his child." She smiled widely at pure shock Castiel displayed at the revelation.

The treachery ran deeper than he thought and he could see by the way Leah was glaring at Lilith, that demon for once spoke truth. Leah was getting tired and Castiel was not helping by just standing there.

"Hey, bitch." She called out.

Lilith's head snapped in her direction and her expression became one of a shock seeing a banishing sigil written on the wall. Before she could act, Leah murmured something and Lilith vanished.

"I'll kill you next time, bitch." Leah pretty much muttered to herself.

As if on cue, two angels from Castiel's garrison burst in, both covered in stench of demon blood. Castiel suddenly unfroze and three of them looked at Leah. Not liking their stares, she raised her blade.

"Just because I'm poisoned doesn't mean I can't fight you." She warned in low tone.

"Castiel, we should capture her and question for answers." One angel spoke.

"No." Castiel replied, much to their and her surprise.

"No?" the other one asked in disbelief.

"I gave my word to Dean Winchester that she will be unharmed." Castiel replied and turned to her.

"You may go." He said and she laughed.

"As if I need your permission to go anywhere. See you, bible soldier." She said and disappeared, leaving Castiel to ponder over the new information he got.

Back at Leah's house, Ruby and Alana busied themselves around Ena, healing her and cleaning her, while Dean and Sam anxiously waited in her vast living room for Leah's return. The sudden flutter of wings made them look over to terrace exit.

"Leah." Both of them cried out when they saw their friend.

She was covered in blood, her shirt was shredded and she looked drugged. What made their blood freeze was the fact that her eyes rolled in the back of her skull and she keeled over.

"Leah!" Dean shook the unresponsive nephilim.

"Ruby!" Sam shouted and the blonde appeared in a second.

"What is it?" she asked worryingly as she scrambled to their place.

"She's not breathing." Dean said, looking up to the blonde with utter fear in his eyes.
