Welcome to Supernatural

What Dog Park

They arrived at the lady's house and Cas was standing on the front lawn. He looked relived at the sight of the Winchesters.
"Sam, Dean, I'm glad you're here." He said.
"Why are you here, Cas?" Sam asked.
"That's the thing- I don't know." Cas said then there was a gasp.
"You're really an angel?" Cecil said, astonished.
"An angel should be he least of your problems.." Dean muttered.
"Yes, I am an angel." Cas said.
"It's an honor!" Cecil exclaimed, "Am I even worthy?"
"Um..I'm sure you're..worthy." Cas said then pushed around the strange man to get closer to the Winchesters, "we need to get out of here."
"Why? What's wrong?" Sam asked.
"I feel a strong..I don't know.. Presence. Evil. Something..." Cas replied.
"Where is it coming from?" Dean asked.
"Everywhere. It's absolutely everywhere." Cas answered.

"I can teleport to the border but not out of the town. I also can't teleport into the dog park for some reason." Cas said.
"SSSHHHH!" Cecil suddenly blurted out, "we do not speak of the dog park. Do not even acknowledge the dog park exists." Cecil looked stern yet afraid. An emotion that made no sense.
"Um..sorry." Cas said.
"why? What's so bad about the dog park?" Sam asked.
"Let us change the subject."
"Really? It's just a dog park." Dean said, "there can't be anything so bad about it."
"Be quiet! The secret police can hear us! We do. Not. Speak. Of the dog. Park." Cecil said, "there are eyes and ears everywhere."

"Huh...alright then...." Dean said.
"Let's leave this town to themselves." Cas said, "I know that we do not have enough power to help them. From what I have seen they have their own...special way of living."
"I don't see why we have to leave yet. There's gotta be an actual case here." Dean said. Cas turned to face him.
"They have banned all wheat and wheat by products. That means no buns for burgers and no pie either." Cas said.
"Let's leave. Now. Right now." Dean said. Sam laughed.
"That's what I thought." Cas said.

They turned and started walking back to the radio station. Cecil trotted behind and started talking.
"You should stay for a bit- we have many tourist attractions. Like, the harbor that never exist nor will ever exist. Oh! And Carlos. Carlos the scientist and his perfect, perfect hair. He's smart. And perfect."
"Uh-huh." Dean said. And then they passed the dog park. Cecil looked in the opposite direction innocently but Sam, Dean and Cas looked right in. Then they saw the shadowy figures. Dean stopped and looked at them.
"Who are they??" Dean asked.
"Aha, I don't know what you're talking about. Haha. There's no one. Haha." Cecil said, "keep walking."

Suddenly one of the figures turned to look at Dean. Then it was gone.
"Huh." Dean said then turned to start walking, but standing in front of him was the shadowy figure. It started making a horrible, loud, radio static noise. Dean, Sam and Cecil covered their ears but Cas listened. Dean fell to his knees, groaning as he felt like his brain was going to explode because of the noise. Castiel stepped forward and places his hand on the head of the shadowy figure. The figure glowed white then disappeared. But what Cas was horrified to find out was that Dean had disappeared too.
