Was Lou Grant gay?
I know he was divorced, but I always got the impression there was an underlying, unspoken theme that Lou was gay.
Starrbeat presents what's happening.
No, I always read him as a heterosexual who isn't very good at being a heterosexual.
Knows he's not physically attractive, has no small talk, gruff and cynical, hesitant to open up to anyone after a failed marriage, thinks he has no chance of finding love again (if he ever did), etc. Willing to go out on the occasional date if an opportunity falls in his lap, but burying himself in his work rather than actively looking.
