Dean has Ghost Sickness. He's been infected by a ghost, which causes him to be scared of absolutely everything. He's like a little kid currently. Sam is honestly so done with it, but he still obviously cares and loves him enough to stick around and help him over come this. You and Dean had been dating since the year after high school, and you're also a hunter. When Sam called and told what was happening, you came as soon as possible. Though, you were definitely there today when Dean screamed and got scared of a cat jumping out of a locker at the wood factory. You're currently sitting on one of the beds in the motel room, while Dean is sitting in a chair, and Sam is doing his usual research on the laptop.

Dean: Sooo...what now? I'm bored.

Sam: Relax, Dean..
