I should know the name of this one, but it has slipped my mind.

In the fic I'm thinking of Brian and Justin meet in a liquor store when they literally run into each other.  They exchange some not very nice words and then Justin suddenly has a massive headache and collapses.  The paramedics show up and think that Brian is Justin's friend and so he goes to the hospital with him.  I can't remember anything that happens after that.

I know someone out there knows this one...

Anyone?

EDIT:  After days and days of searching I've finally found this one...it's "Finding Home" by turtletwins.  Here's the link:
