Okay. What does Charlie call Alan? "Dad"? That's my best guess, even if my inner ear keeps giving me that word in *Don's* voice.
Specifically, this fic is limited 3rd-person, Charlie's POV, and is basically a conversation between Alan and Charlie. So I'm confused as to how to refer to Alan in the story...since I doubt that Charlie thinks of his father by his first name.
Thoughts? Canon reference? Anything?
