"Dammit Sam, we gotta get outta here," Dean muttered impatiently, his tone getting increasingly more annoyed. Sam knew what that meant, his concerned brother was getting nervous about the rest of their group. "Is there any way to get that freakin' grate off?"

Sam finally managed to get the grate unscrewed using his car keys. He lifted the lid and carefully placed it aside as quietly as he could, although it still elicited a slight metallic sound as it hit the cracked concrete.

Shit.

He stopped moving, listening anxiously for any sound of approaching steps. Nothing.

"Anything," Dean inquired. "Is the opening big enough for us to squeeze through?"

"No, it's just a drainage system. There's no way a kid could get through there, Dean. Are you still trying to pick the lock?"

"Yeah," his brother grunted, "but there's no way to get this open and I don't have the leverage by myself to try to raise the door off the hinges. You?"

Sam tossed his hands up and ran his fingers through his disheveled hair in frustration. He reasonably knew if he felt irked that Dean was in panic mode.

"Dean, we'll find a way out-did Ab-"

"Don't say that name," Dean demanded. He could feel the tension through the wall. Sam knew why his brother couldn't deal with her right now. But Sam couldn't bring himself to fully believe she would have attacked Dean without some sort of motive. What Dean had said to Sam didn't make any sense. But he also knew that once you truly hurt and broke Dean's trust, there was no going back. His brother was now a man on a mission.

"Did you find out anything when they had you? Why do they have April?"

"I don't know, man, it's somethin' to do with Lilith, but they didn't go into details before the bloodsuckers were on me. Either way, it's soon, and we've got to get the kid outta here pronto before they-"

"Before they what-"

"Shh," his concerned brother silenced him.

"What?"

"SHH!"

Footfalls on wet pavement headed their way.

"Sam, do you still have anything to fight with on ya," Dean asked.

Sam checked his person and found they hadn't checked his boots for any weapons. Yep, he still had his knife.

"Dammit," Dean swore in a whisper. "My knife's gone."

"You mean Ruby's," Sam huffed. "Dean-"

"I must have dropped it when we were running or fighting, I don't know. I still have one syringe of DMB. I grab, you stab, ok?"

"Okay." There was still a brick wall between their cells. But if he could persuade whoever it was to stand between them, Dean could get a hold of him for sure. And with his reach, he'd have a good chance of slicing.

The big vampire came up to Sam's cell as Sam was putting the grate back on.

"Hey, what's goin' on," he hissed. He moved to get the specific keys to unlock the cell.

The keys.

Sam stealthily moved to the cell opening.

"Nothing, nothing, it was just loose," he convincingly played, trying to convince him to not open the door. Good, right where they needed him.

Dean's arm emerged from the other cell and he smashed the vamps head into the brick wall hard. Sam grabbed the vamps arm and grasped his knife and sliced his throat to the bone. The vampire gurgled on his blood and fell to the ground. The keys laid beside the battered body.

"Guess I didn't need that DMB after all, huh, Sam," Dean joked. "Now let's figure out the fricken key and let's get the Hell outta Dodge."

Sam reached for the keys and frantically tried all three keys in the lock. Naturally, it was the last one he attempted. It was always the last one they clumsily tried.

"Got it," Sam exclaimed as he rushed to Dean's cell, hastily opening the cell door with a click. The iron door creaked open. "Cas? Are you awake," he whispered tensely.

"Ow...yeah, I'm over here," Cas gratefully answered. Sam quickly unlocked his cell door and both boys helped Cas to his feet. He was not in good shape. The yanked leg during the earlier scuffle and capture appeared twisted at a strange angle. And from the dazed look and constricted pupils, he presumably sustained a concussion at the very least.

"Now, how the Hell do we get out of here," Dean questioned, his critical eyes taking in their dark surroundings. There was only a hallway in front of the cells, forcing their only choice of going left or right down the equally darkened hallways.

The boys, while supporting Cas, ran up one way and found a door. Locked. They desperately tried a few of the keys they took from the deceased vamp. No luck. They discovered another passage. Another locked door, and still no decent luck with their keys. They went back towards the dingy cells to the other end. Another secure door, but this time key number two worked. It promptly opened to the outside. The unclouded moon shone serenely on the grass field leading up the gentle hill to the security of the treeline. Sam instantly found it odd there were no longer vigilant guards posted visibly around the building. Regardless of what they could perceive, they had to be on their guard and ready for anything. Vampires were fast and unpredictable, and they were not well-armed.

"We can't leave April here, Sam, we gotta find a way to get in there," Dean demanded passionately.

His devoted brother was now officially in full panic mode alright, and when he was in that state, Sam knew Dean was completely irrational. All of their weapons were gone. There was no way they were going to take out a whole slew of vampires with just one knife and a few syringes of Dead Man's Blood. That was a death wish and would be helping no one. They needed to regroup and gather reinforcements.

"Dean, we've got to get Cas to Gwen, and we need to check on Dylan. Then we can get back here. They need April for something. They're going to keep her alive. But this place is a maze and if we just find a way to run in there with no weapons, we're dead. If we're dead-"

"She's dead," he grudgingly conceded with a sigh. "Okay, Sammy. Let's roll." The trio snuck out of the back door of the extensive building. They hurried swiftly towards and through the woods and back to Sam's SUV, quickly getting in and slamming the doors. Dean put in the keys, set it into gear and took off.

"We have till tomorrow night, Sam," Dean said. "Whatever the Hell they are doing, it's powerful shit to do with Lilith, and what usually needs to happen to supercharged mojo?"

"Celestial events," Sam suddenly realized. The Dark Moon was the next evening.

"We don't have much time to dick around, we need a plan."
