"Why did Emily just walk out without you?" Dean cocked an eyebrow as Castiel approached him two minutes later.

"She made it clear she didn't want me to follow," Castiel explained. "At least not tonight."

Dean smirked. "Which means probably some other night than?"

"I don't know," Castiel sighed.

Dean glanced at his watch. "I guess we'd better get going."

Castiel agreed.

"Ready Sam?" Dean inquired as he turned to face his brother.

Sam yawned. "Yeah."

He stood and led the way out of the bar.

As they made their way to the Impala a scream rang out in the moist air. Dean, Sam, and Castiel all were alarmed. They immediately bolted towards the direction in which the sound came from. They ran around the building to the back to find Emily on the ground with one of the biker men standing over her, ready to kill her with a knife.

"Get away from her, you son of a bitch!" Dean growled.

The biker man looked up at him and his eyes flickered black. He was a demon.

Dean pulled a bottle of holy water out from his jacket and splashed the demon's face with it. The demon shrieked in agony and turned on Dean.

Sam began reciting a Latin exorcism but the demon reared his meat suit's head and left his body before he could send it back to Hell.

When it was over, Castiel kneeled next to Emily, concern written all over his face. "Are you hurt?"

"I'm fine," Emily reassured him.

"What happened?" Sam asked as he was trying to catch his breath.

Castiel reached out to Emily and she grabbed his hand so he could help her to her feet.

Once she was standing, Emily answered Sam. "I was walking to my car and out of nowhere that demon attacked me."

"Have you ever seen the demon before?" Dean questioned.

"No, at least, I don't think so," Emily said. "I don't normally hunt demons. I've only hunted one and I sent it back to the pit. It shouldn't have been able to escape so soon."

"Did he say anything to you?" Castiel asked.

Emily pondered for a moment. "He did mention something about killing me to save his species."

Dean frowned. "Why would he consider you a threat to all demons?"

"That's what I'd like to know," Emily snorted.

They all fell silent for a few seconds, each trying to think of why Emily was attacked. None of them could find a good reason.

"Well," Emily spoke up finally. "I'm going to go. Thanks for saving me. I guess we're even."

She was about to turn and leave when Sam grabbed her left arm. "Not so fast. You need to come with us."

"But…," Emily began to protest, but Sam interrupted her.

"The demon is still out there. It would be safer if you stuck with us until we get him."

Emily glanced back at her silver car, a pout on her face; then looked back at Sam. "Fine, but I'm taking my car with me. I'll follow you."

"You'd better," Dean said. "Or else we'll track you down and we won't be very happy."

"Don't worry," Emily assured him, rolling her eyes. "I'm not dumb enough to go against orders from two experienced hunters like yourselves."

"Good."

When they arrived back at the motel, Sam went to the front desk and got Emily the key to a room next to his and Dean's.

Once Emily had brought her bags into the room she joined the brothers and Castiel in the next. They were discussing how they would protect her and possible ways of finding the demon.

"So what's the plan?" Emily inquired.

"We're going to start looking for signs in the morning," Dean updated her. "For now, Castiel's staying in your room."

Castiel lifted his head, his eyes wide with shock. This was news to him.

"I don't need anyone to watch over me," Emily argued.

"Please? I'll sleep better tonight knowing you're safe," Dean pleaded.

Emily sighed. "Then why don't you do it?"

Dean grinned. "It's not up for discussion."

Emily huffed, "Fine."

She stalked out of the room and Dean twisted around to see Castiel glaring at him. He was not happy with Dean at all.

"Cas, don't you have to go?" Dean laughed.

Castiel glanced at the closed door then back at Dean with his intense eyes.

If looks could kill…, Sam thought...Dean would be a dead man.

Castiel lifted his bag onto his shoulder and carried it with him as he left the room. The door slammed shut behind him.

When Castiel entered Emily's room she was sitting in a chair by the window. She watched him as he walked over to the second bed in the room silently and dropped his bag onto it.

"He's trying to set us up, isn't he?" Emily mused.

"Yes."

Emily shifted awkwardly in her seat and Castiel noticed. "I could probably get Sam to stay in here instead of me."

"No…it's okay." Emily smiled. "I trust you."

Castiel pondered what that meant for a moment, then sat down on his bed. Emily stood up at the same time and headed towards the bathroom with her bag. "I'm going to go get ready for bed."

Castiel nodded and watched as she disappeared into the room before lying down, fully clothed, to rest his head on his pillow. He was exhausted from the lack of sleep he'd had since rescuing Sam and Dean.

In a matter of seconds, Castiel was sleeping soundly.

The sound of glass shattering and a thud as something heavy hit the ground, startled Castiel from his rest three hours later.

A balding Caucasian man was standing tall amongst the broken glass. He had entered the room by running through the front window.

His face was all cut up and his eyes were dark.

The demon must have followed us from the bar, Castiel thought.

Emily, who'd awakened at the same time as Castiel had, jumped out of bed and backed away from the demon to distance herself from him.

Castiel shielded Emily with his body and grabbed the demon killing knife Sam had given him earlier in the Impala. He held it in front of himself and focused his eyes on the monster before him.

"I'm not going to let you destroy everything," the demon sneered. "Even if it's the last thing I ever do."

"Oh, it is," Dean yelled as he stormed into the room with the Colt in his hands.

The demon gasped and as he twisted around to face him, Dean fired the Colt. The bullet hit the demon directly in his heart.

Bull's eye.

The demon starred at Dean in disbelief then collapsed to the floor, dead.

"Are you okay?" Dean asked Emily and Castiel as Sam stepped out from behind him to survey the scene.

Castiel and Emily quickly nodded.

Emily sighed. "I am now."

The next morning Emily ate breakfast with Sam, Dean, and Castiel at a diner in town. As they did so, they talked about the demon which had attacked her.

"I'm glad we got rid of him quickly." Emily smiled. "Now I can finally leave this town."

"Wasn't as hard as I expected it to be," Dean said. "He was suicidal apparently. Attacking you twice on the same night without checking out who was with you."

"Not suicidal, determined," Castiel corrected him. "The demon once again mentioned why he wanted her dead. Still was too cryptic of a message for even me to understand though."

"Same line, different verse," Emily added. "It doesn't really matter now. He's dead."

"So are you heading out today?" Sam questioned.

Emily bobbed her head. "Yes, I most certainly am. When we get back to the motel I'm going to pack my bags. The motel owner's not very happy with me right now. You sure you can afford to pay the window?"

"We have credit," Dean explained.

"Yeah, I know," Emily snorted. "Other people's."

Dean ignored her comment. "So where are you going to go?"

"Any place down south," Emily answered. "You?"

"Connecticut," Dean replied. "There might be a witch to hunt in Hartford."

"Sounds fun." Emily then turned to Castiel who was pushing his mostly empty plate away from himself. "And what about you?"

Castiel shrugged. "Don't know. I guess I might head east too."

Just then Kay, the group's waitress, arrived with everyone's slips and they pulled out their money to pay her.
