How does the relationship between abigail and elizabeth proctor affect the outcome of the crucible?

In a neat literary twist, Elizabeth's positive qualities are also her negative ones. She is a virtuous woman who is steadfast and true—but these traits also make her a bit of a cold fish. When we first meet her, she's especially cold...and thinks she smells something fishy. She's got good reason to be suspicious and kind of distant, though: her husband has recently had an affair with their housekeeper, Abigail Williams.
