Molly did it all so Emily could have Draper. You see, April was supposed to visit Raven where Molly was going to poison her, but Nadine (Raven's mother) showed up and drank the poisoned tea instead and she crashed her car and died. Molly told Eliot that she saw Raven give Nadine the tea, but Eliot was onto Molly so she killed him . She also stabbed Cliff because he was starting to put two and two together. She faked the attack by Kelly to cast the blame on him.
The Edge of Night used to come on here in NYC at 4pm and I remember it like yesterday when Molly confessed to Raven about all she did. It was on a Friday and I had to be back at my high school for something. I did not move from in front of that television until the closing credits at 4:28 pm.
IMHO, no soap has come close to Edge as far as good mystery and the intertwining and segueing of stories.It just makes me so sad, the state of the soaps today. What happened to good storytelling? BTW Chris Goutman (EP of ATWT) played Sharkey who got Emily pregnant.
