Justin feeling not worthy

[mulderbuz.livejournal.com]

I'm looking for a fic I read a long time ago (2 or 3 years, maybe even more) but it couldn't leave my memory (sort of since I didn't keep a trace of it). It was a one shot, well written (if I remember well).
It was post reunification in season 3, maybe season 4 or 5. Justin analyse all his interactions with others (Debbie, Emmet... and of course Brian) and realize he must be not "essential", worthy.
I remember at the end, in the Diner, he thinks leaving Pittsburgh alone, and Brian tells him he'll go with him.
I check many tags and memories and didn't find anything.
So you're my last chance. Thanks.
