The gang realizes B&J´s interaction

[fort1luna.livejournal.com]

I´m looking for fics in which someone of the gang realizes how Brian and Justin interact in their every day routine or in their affection for one another, so that he apprehends what they feel for each other. I´m thinking of something like the story in which Emmet has to stay at Britin because of heavy snow. He sees the two interact and understands a lot more of their relationship then. Are there any similar stories out there?
Thank you!
