Andrea Comes This Close to Murdering the Governor (Episode 11, 'I Ain't a Judas')
When Andrea pays a visit to her friends living in the prison, they urge her to abandon Woodbury, or at least to put an end to the Governor's evil machinations. During a girl-talk catch-up, Carol urges her to sleep with the governor to make sure he's not suspicious and then murder him after giving him the "night of his life.”"Whoa, Carol! We didn't know you had it in you! Excellent plan – wear the Governor out with a lusty bout of sexual healing and then kill him in his post-orgasmic slumber. Andrea returns to Woodbury and (we assume) has some hot and heavy bedroom time with the Governor. She slips out of their bed while he snores in post-coital bliss. She grabs her knife and holds it to his throat, but hesitates at the last minute and loses her chance. A nation of fans moan and groan at her decision. Dangnabbit, Andrea! You were this close.
