Brotherhood AU story - FOUND in comments

[antigone11.livejournal.com]

I've checked the mute!boys tag and various other sites and haven't been able to find this story.  It's set in the Brotherhood AU.  Dean is mute after Mary's murder and John ends up taking him to Dr. Mackland Ames.  The story is primarily about a teenaged Caleb meeting four year old Dean for the first time and I think he ends up having to look after Dean for a while.

I have checked the Hunter's Tomb site and Ridley Scott's fanfiction.net page and still can't find it.  I'm dying to read it again so I hope someone can help!
