Are you telling me I can't be disgusted with Lee for when he was all "just your insecurities, Dee! Ever since the day I proposed! And I can't feel superior to hardcore Lee fans when they go on about how he's so much more moral and upright than Kara and he never really wronged Dee or anyone else, never? BECAUSE I NEED MY FEELINGS OF SUPERIORITY, LYSSIE!

But yeah, I never happened to ship Lee/Dee, but that doesn't mean Dee sucks as a character. (And I do think Lee loved her.) Even if she was in a horrible, retconned Cally/Chief like marriage, that still doesn't make her a horrible character. It just makes her a character who didn't lead a charmed life.
