Looking for Dean/Castiel FanFic.
What I remember is that Dean was depressed. He ran away and rented a flat over a florest shop. I am not one hundred percent sure but he may have painted. Cas and Dean has twins and Cas was so upset because Dean had a child in the pass and he thought that this child had died and he was put back in a mental hospital. Castiel did not know what to do, having two babies to look after. He visited Dean in the hospital, and told him he would not leave him. I had a feeling that Hitchcock's Birds come into it some-ware but I have read so many fics I may have got that mixed up. I remember it was sad but it was a good fic to read.
