Dean in “Unfinished Business”

Dean

[to his Dad's voicemail] Dad, I know I've left you messages before. I don't even know if you get 'em. But I'm with Sam and we're in Lawrence and there's something in our old house. I don't know if it's the thing that killed Mom or not... but... [tears up] I don't know what to do. So whatever you're doing, if you could get here... please. I need your help, Dad.
