Hullo,
I went on a reading binge last night and in my state of dazed remus/sirius didn't bookmark. I tried to retrace my steps but didn't turn up the ones I liked especially, so hopefully you guys can help me! :)
The first one had a prompty bit in the beginning that mentioned how Peter was not a major character but had a strong presence (he was already working for Voldemort and is trying to distract the gang by accusing Remus of being the traitor). Sirius is sent to "spy" on Remus, but instead ends up spending Christmas with him and his elderly father. There's a scene with a photo album! They decorate a tree very badly together.
I can only remember one part of the other one. In a flashback (or something?) Sirius is dancing with Lily at her wedding reception; Lily refers to James as Potter, and Sirius says that she's a Potter now too but keeps calling her Evans. I thought the banter was adorably in-character and I'm definite there was R/S in it.
Found it! It's

Thanks loads! I really appreciate it.
