The PFLAG group continues to meet and Burt comes to a meeting and even Dave's dad, Paul, comes to a one. I can't remember if Dave came out to his dad in one of the meeting or if he just talked about doing it. The story then continues into the future. They all go to college of some sort and Dave keeps in touch with Kurt and tells him about boys he likes/meets. Finally he brings a boy for Kurt and Blaine to meet, but he needs some kind of closure/forgiveness from Kurt before he can really confess his feelings to this new boy. I'm pretty sure Dave becomes a professional football player, and end up kissing the boy he likes after they win a big game, if that helps.
Thanks in advance! (Mods, I hope I did everything correctly! Let me know if I need to fix anything)
