As the Impala stopped in front of Caroline and Jack Barnes, Sam noticed the dog barking at the house. "Dean don't you think it's weird that that dog is barking at that house?" Sam said looking at Dean. "Yeah it is, but they probably have a cat, so I wouldn't worry about it too much," Dean said getting out of the car. Sam opened his door and climbed out of the car. "Dean, wait, what are our cover names this time?" Sam said. "I think will go with Reedus and Flannery, I liked that movie," Dean said. "Yeah it was a good one. Ok, I'll talk to Caroline and you talk to Jack," Sam said as they walked up to the door.
Dean knocked on the door. As they stood there waiting, they heard the sound of someone getting up from a chair. A young woman with bright red hair answered the door. "Yes can I help you?" she said. "Yeah, I'm Special Agent Flannery and this is my partner Special Agent Reedus. We're looking for Jack and Caroline Barnes," Dean said as he and Sam pulled out their fake FBI badges. "I'm Caroline, my husband Jack is in the living room. What's this about?" Caroline said. "It's about the noises that you and your husband heard last week; we've had some similar reports in other states. We're going around and clarifying some of the witness statements and we were the closest ones to you," Sam said.
Caroline stepped aside and invited the men inside. "Jack we have company. The FBI is here to ask us about those weird sounds we heard last week," she said as they entered the living room. "We already gave our statement to the police. So why is the FBI interested in it?" Jack said getting up off the couch, reaching his hand out to shake hands with Dean. "As my partner told your wife, we have had reports of a similar type in a few other states which is what brings us in," Dean said shaking the man's hand. "Oh, well, that makes sense. Well as I told the police, my wife and I were taking a walk around the park, when we heard a sharp whistling noise from one of the abandoned buildings nearby. It was quite loud. I'm not surprised that other people heard it," Jack said indicating with his hand for them to sit. "Can you give us a description of what it sounded like?" Sam asked. "I can do you one better. I have it recorded on my phone. I didn't give it to the police because, well, frankly I had forgotten about it," Caroline said.
Caroline got up, walked over to the end table by her husband and grabbed her phone. "I noticed that I had it recorded when I looked at my phone last night. I didn't even notice that I had the record setting on, but apparently I did," she said handing the phone to Dean. Dean pressed the play button and a loud screeching sound assaulted his ears. "Wow, that didn't even sound human. Is there any way you could email this to me?" Sam said. "Yeah, let me get your email real quick and I'll send it to you," Caroline said as she and Sam headed out of the room.
Dean sat back and studied Jack for a few minutes. "What do you think that sound could have been?" Jack asked him. "Not sure, but when we get the email, we'll definitely have to analyze the sound," Dean replied as Sam returned to the room. "Thanks for your time. We have to get to the next person and see if there any anomalies in the stories. We'll contact you if we have any other questions," Sam said heading towards the front door. Dean followed Sam and Dean got in the car, Sam turned to Dean and said, "What do you think?" "Not sure Sammy. But whatever it is, it ain't human," Dean said.
