Corrected entry: When Rosemary gets onto her computer to look up "Withersedge", without touching the keypad, about ten sites appear on the screen. Then she types madly, but what's on the screen doesn't change. And then by magic, she finds the exact site they need - the one about Mrs Potts. And when she unplugs the computer so Laura can use the phone, while Laura is talking on the phone, Rosemary stares at the computer as if it's still on, but it isn't.
Corrected entry: Rosemary finds a bottle of Betabuse in Marcia's medicine cabinet. Betabuse, Rosemary tells Laura, is for alcoholics, who, while taking Betabuse and alcohol will throw up. Eventually, the alcoholic learns to equate drinking with vomiting. Jeremy, Marcia's husband and the alcoholic, is found dead from a heart attack. Marcia is arrested for killing him, because she (1) made him mushroom soup, using smooth ink cap mushrooms, which have the same ingredients as Betabuse, then (2) replaced the water from his water bottle as he went jogging with vodka. The police say Marcia hoped that when he took a swig of water and got Vodka instead, after eating the soup, it triggered a heart attack - now, yes, Jeremy had a "dodgy ticker", but throwing up is a far cry from dying from a heart attack.
