I read this fic a long time ago that was set soon after Mary died. John was very drunk and Dean enters the room. He yells at Dean about how upset he is that Mary died and, when Dean starts getting scared and crying, he yells him to stop crying. It's from John's POV and he's thinking that he should really stop yelling at Dean, but he keeps going.

Any other fics that have little Dean dealing with upset or drunk John would also be appreciated. Thanks for any recs!
