I'm looking for a fic, I believe it was post 513. Justin has been away for several years and returns to the Pitts. Gus is a teenager, and he hates Justin, because Justin is the man who broke his father's heart by leaving. It's told from Gus's point of view, and he keeps saying that Justin has big ugly teeth. When Justin and Brian see each other for the first time, they share an awkward hug, and Gus is all happy and smug about it, but the next time he sees them together, they're all over each other, and he gets kind of annoyed, but eventually it all works out. Does anyone recognize this?

Edit: fic is 'The Evil Ex' by suzvoy, link can be found in the comments
