Would Brady count, hmmm....that's an interesting question, one that I need to ponder for a bit.
This is OT, but one of my favorite portrayals of a parent on the show was by Rebecca Schull; she was A steer Gruenwald, mother of Harveyk, in "Unrequited". She wasn't what I'd call a kind woman, but she did have Harvey's bets interests at heart. She was a great character, but not a great parent. That's still one of my favorite episodes; every character is played perfectly.
Do you think Priscilla Van Acker ("Smothered") qualifies as a "good parent"? She thought she was helping her son, but she orchestrated the murder of a woman that truly lived her son.
