No, Jack is Brian's dad in "Be Careful What You Wish For." Brian finds out that Jack had a brother who was gay, and that Jack had cut his brother out of his life when he found out. Brian's uncle contacts Brian post-Jack's death and shortly before his own. It's more of a "Brian and Justin meet in a different way" fic.
