Tracy telling Peter he's the black sheep
Really? She reckons she's nowhere near as bad as him no matter how hard she tries! OK, he's an alcoholic and serial womaniser/cheater. He's not done anything that can be considered really bad. Most soap characters have affairs and many succumb to addictions and stuff. Yet, Tracy has murdered, blackmailed and behaved in totally reprehensible ways towards people. She tried to blame Beccy of pushing her downstairs causing a miscarriage, she tried to fool Roy into believing he was Amy's father. She blackmailed Carla to get Nick to sell the Bistro and move away. She is cruel and dishonest and she thinks Peter is the bad sheep! Peter is a pussycat compared to her.
Peter is obviously in trouble and been up to no good, but I doubt he's ever going to be on the same level as Tracy when it comes to being despicable.
