She was placed aboard the flight in the guise of a flight attendant to support Ring agent Hugo Panzer during his mission. Serena freed Panzer after he was disabled in the cargo hold, and poisoned Chuck to force him to return the key. She was later incapacitated by falling luggage after Sarah took control of the aircraft via satellite and destabilized it, and was apprehended when the flight arrived in France. Shaw expressed a familiarity with Serena's tactics, and implicated her in several poisonings of high-ranking officials.
She appears in: "Chuck Versus First Class".
