De-aged Dean

[wastedjamie.livejournal.com]

I am trying to find a story that has de-aged Dean.  I've read it a few times years ago and forgot to save it :(  I remember that Dean and Sam are hunting something and Dean gets de-aged.  They call for John and he meets them at the motel.  De-aged Dean opens the door without checking and John scolds him for it.  Dean gets frustrated being de-aged and throws a cup of coffee against the wall.  John gets frustrated with Dean's behavior and punishes him for throwing the cup.  That's all I can remember.  Thanks for the help!
