Thinking about an AU where Durge remembers more than they do in canon and they and Karlach end up getting into an argument about Gortash (either because Karlach got too aggressive about him or Durge got too defensive of him) and Karlach demands to know why Durge is so protective of the man after everything he did to the city and its people and her, and Durge just looks at her and says very gently "He's the only person who's ever wanted to know all of me."
