Looking for a post-Hogwarts fic during the war

[sostrata]

Hi, I'm looking for a fic that was set in the First War. I'm pretty sure it wasn't an AU- if so, it wasn't a big AU. It would have been written in 2006-8. I read it on lj. It's R/S, and also featured James and Lily. I think that Sirius was a healer. At any rate, he had some role that wasn't as front line-sy as the others'. What I mainly remember was that Dumbledore doesn't trust Sirius and likes to keep him out of the loop. I remember someone (James?) not realizing this at first. There's a confrontation about this.

Any ideas? Thanks in advance!

ETA It's been found! It was Fondness Makes the Heart Go Absent by red_squared.
