In last week's episode, Concordia (airdate: 2/8/11), newscaster Chad Decker debates Kerry, a potential sparring partner who opposes Anna and the other V's:
CHAD: Beware of Greeks bearing gifts?
KERRY: Exactly. The Trojan Horse filled with soldiers. Smallpox-infected blankets for the Native Americans. These gifts didn't work out too well for the recipients, did they?
CHAD: But Anna has demonstrated the utility of her gifts. We have clean air, and revitalized deserts, to prove it.
KERRY: And I'm sure the Native Americans were warm in their blankets before they started dying in them.
