She had a tough exterior, but she was soft deep down. I loved her rivalry with Will Schuester and the entire Glee Club. She was absolutely hilarious throughout her entire show. I loved her obsession with Madonna. I loved her obsession with herself, even going on to marry herself LOL. But my favorite thing about Sue, is her friendship with Becky. She is a bitch, but she always has Becky's back. Sue's sister has downs syndrome, so she has a soft spot for becky. Even when Becky shoots the gun, Sue sticks up for her in probably my favorite scene in the entire show <3
