I read a fix-it fic where Shep became like a reaper AI after the end decision and she spent 10 years bouncing around the galaxy from network to network collecting all 1183 programs and then having the geth build new bodies for both her and Legion
And she sent out a message to her old crew and Garrus and Tali were married on Rannoch and Steve and Kaiden were together and Grunt had a position in Clan Urdnot and they all met and hugged and AHHHH MY GOD IT WAS SO CUTE
