Once he got Ronald up to speed on what the actual situation was, they did a search of the place and found that it had already changed forms. Ronald was fully on board and trusted Dean now that he was agreeing with his theories. As they headed for the lobby the power went out. Shit. The cops had arrived.

They went back to the vault and moved the hostages, as well as let Sam and Kayla out to help them catch the thing. He gave them each the few sharp pieces of silver he could find.

Sam was worried when he saw the police lights. "Even if we catch this thing, how the hell are we gonna get out of here? You're wanted by the police!"

"One problem at a time." Dean glanced over his shoulder. "Ronald. Out of the light!"

Ronald took a step back and nodded to him.

Kayla lowered her voice. "He's going to get hurt Dean."

"Which is why you should stay here and help him manage the situation while we go look for this thing. Yell if you see anything."

She nodded and leaned against one of the counters. The guys took off in opposite directions and she looked at Ronald with a reassuring smile. "Don't worry, they've dealt with shapeshifters before."

He nodded a little, he seemed nervous to talk to her.

"Maybe we should check on the hostages, make sure everyone is where they're supposed to be."

"Um, yeah that sounds good." He followed her to the back, as they were approaching the phone rang. Kayla ignored it and went for the hostages, Ronald stopped and answered the phone.

The old guard was collapsing, he appeared to be having a heart attack. It could be a trick, or the guy could really be dying. Talk about a predicament. Ronald was talking to the police, giving too much information and Kayla walked over and hung up the phone.

"The less they know the better, ok? Like you said, they won't believe you."

"This guy is having a heart attack!" A man yelled at them.

She sighed and looked at him, she didn't know what to believe. "He could be it Ronald, it could be a trick."

"You're just gonna let him die?!" The man was trying to hold the guard up.

"No one's gonna die!" She grimaced and picked up the phone; she told the police to send in a paramedic immediately.

Dean came back with Sam, Kayla walked over.

"It's shifted again, it's the black guy." Dean told her quietly.

She looked into the vault. "Um, Ronald I think he's right. We should get this man out of here, now before something happens. You don't want him to die do you? That's not what you want."

Sam helped the guard out the door, Kayla went with him to bring him to the front.

Dean glanced to the man. "Can I talk to you?"

"Hey, you've got the gun man." He stepped out and suddenly knocked the gun out of his hand while slamming him into the wall. The guy took off running. Dazed, Dean picked himself up and ran after him.

They all saw him run by and Ronald yelled him, chasing him with the gun. He stopped in the lobby and raised his gun.

Sam saw red. There was a laser on his back. "Ron get down!" He screamed, but it was too late. A silent bullet ripped through his back and out his chest; a kill shot.

Kayla covered her mouth and Dean jerked her against the wall to keep her from getting hit, just in case they fired again. Sam came up to them and gave Dean the key to the doors.

"Take care of the guard, I'm going after the shifter."

Dean watched him go and slowly approached Ronald motionless on the ground. "Sorry Ron, you did a really good job tracking this thing. You really did." He looked at Kayla. "Stay here, I'll be right back."

He took the guard out the front door at gunpoint to keep from getting himself shot. The place was swarming with cops, SWAT team, FBI, you name it they were there along with the news crews. They were so screwed. He went back to Kayla.

She put her phone in her pocket and looked at him. "Sam said it changed again, could be anyone."

"Great. Let's see if anyone's missing out of the hostages." They went back, a phone on the wall started ringing and Dean answered it.

Kayla checked on the hostages. From the gist of the conversation Dean was having, there was a cop out there who knew a lot about him.
