I haven't watched it in a few years but I use to love the show & I wondered how they would resolve the triangle.
Thae gang returns to Capeside for Dawson's mother's wedding. Joey is a book editor living in NYC with Christopher, Dawson is Executive producer of a tv show called *the Creek* storylines similar to their lives, Jen is a single Mom, Grams is still alive and Jack iand Deputy Doug are in love(!) but Doug is still in the closet; this causes conflict. Jack is teaching at the High School. Pacey is owning and running the restaurant in Capeside.
Jen collapses at the wedding, she has a heart defect that was not diagnosed until she was pregnant. Jen asks Joey who she will choose as Joey confesses she loves Dawson and Pacey still. Joey tells Jen her choice has always been clear but that she has been running away from it. Jen dies. Jack, as her daughter's Godfather will get to raise her daughter. At the post funeral *do* Pacey tells Joey that he loves her but is letting her off the hook and hopes that she finds someone who loves her as much as he does. He wants to be happy but knows that he can't rely on someone else to make him happy, he has to do it himself. Joey is about to confess ther feelings to him, says that she loves Dawson and they are soulmates but that is something pure and left over from their childhood. Deputy Doug and Jack make up and will raise Jen's daughter together. At the end, Joey and Pacey are together but the fictional Joey and Dawson, on Dawson's show, get together and Dawson gets to meet Speilberg! Everyone seems happy :)
