He had listened to many of Sam and Dean's messages. Now, he found their father's old voicemails. He thought maybe this could be the hook to reel them in. Unfortunately, John didn't seem all that fond of leaving messages.
The last message he ever left was for Sam. "Sam, where the hell are you? Dean and I are back with our lists. Get back here, pronto!"
He listened to them going back in order.
"Dean, I got your message about Sam being missing. I'll assume you found him if I don't hear from you again."
"Dean, Sam said you were sick. Leave me a message that you're OK."
The next message was garbled, but he could pick up bits and pieces. "Dean, be careful. We're all in danger…."
"Dean, I'm going to check out those killings on Centennial Highway. You go take care of that Hoodoo thing."
"Dean, I'm in California. I'm going to check on Sam. I'll let you know if anything's wrong."
"Dean, meet me at Pastor Jim's. He says he thinks there's a wendigo in the area."
"Dean, have you finished with that research yet? Meet me back at the hotel."
He listened all the way back to his very first voice mail.
"Dean, I'll be back tonight. Keep watching out for Sammy."
Well, at least he knew what his voice sounded like, and which brother was more likely to respond to him. Didn't sound like he called Sam much.
He listened to Dean's messages to his Dad next.
"Dad, where are you? We're worried. Let us know when you're done with Meg."
"Dad, I figured you would want to know. We got that striga. And all the kids that it's fed off recently are better. I'm sorry I screwed up way back then. I hope now you can finally forgive me.
"Dad, we think we have a serious lead on the thing that killed mom. So, if you get this, come to Chicago. We could really use you on this one."
"Dad, Sammy's missing. I think it's some kind of phantom attacker. If you get this, please come help me look. I'm sorry. I know this is all my fault."
"Dad, I'm fine. Sam found some faith healer. Well, he wasn't exactly a faith healer, but anyway I'm fine."
"Dad, I'm in Lawrence with Sam. We think something's in our old house. I don't know what to do. Dad, if you get this please come to Lawrence." It sounded like he was trying hard not to cry in that one.
This had definite potential. Dean would clearly want his father's help. He seemed to call for it often. He wouldn't refuse it if offered. He wouldn't question it because he wouldn't want to.
