The patterns we repeat is certainly one of my fav fics, too. And the one by loveliesfamous, I read it, and it doesn't surprise me that it's awesome. Do you know A Feast in Azkaban by nyxfixx? This is the most perfect fiction I've ever read, and has the most wonderful characterisation of Sirius - at least he's exactly the way as I see him.

Thank you for the recs! They were awesome :)
