Do you think Bashir tells Garak the story of the Prodigal son?
Can't decide if Julian would share it after the internment camp to argue that Tain was a terrible father, or if he'd realize it won't change Garak's mind on anything and it would just hurt him further in the midst of his grief.
Or maybe after DBIP he angrily explains the story as an argument that his own parents were wrong and they never should have augmented him. That for thousands of years humans have told this story and they should have known better.
Or if after The Wire he decides "I must avoid this story in our lunchtime dates because Garak *will* have Very Strong Feelings about it and I don't think he'll handle it well."
I think it works best early on, Season 1 ish. Maybe there’s a reference to “the prodigal son returns” or something in one of their books. So either Bashir explains it or Garak goes and researches it himself.
But then! Years later, after the camp and DBIP, it comes up again for some reason. And THEN! It hits one or both of them on a whole new level
