Round One: Ruth Eastman Replaces Eli Gold
Why: She not only took Eli's job—she and Peter played it to look like it was Eli's idea.
After chasing down Ruth Eastman and begging her to consider meeting with Peter Florrick to discuss representing him for the upcoming presidential election, Eli Gold returned to Peter's office only to discover that she was already there.
Turns out, Florrick had spoken to her before and, upon Gold's return, told his longtime advisor that Eastman was taking the reigns. After supporting Peter through years of scandals and encouraging him to run in the first place, Gold quit on the spot.
"I got you here! You wouldn’t be here without me. When you were polling nothing, when you were banging your freakin' ethics coordinator, I stuck by you!" - Eli Gold
