On February 11, CBS celebrates the 20th season of Survivor by airing an edition that places previous contestants against one another.

However, these aren't just typical, easily forgotten contestants. One tribe will be comprised of supposedly heroic island inhabitants; while the other will be made up of the show's most beloved/hated villains.

Leading into the premiere of Survivor: Heroes vs. Villains, we'll be previewing each returning player. First, it was Amanda Kimmel. Now: Cirie Fields.

Previously seen on: Survivor: Panama and Survivor: Micronesia.
Tribe: Heroes.
Occupation: Nurse.
Best known quote: "If it looks like a rat, smells like a rat, give it cheese!"
Unofficial motto: Kill 'em with kindess.
Odds of winning: 60-1.
