Malcolm Biggs was a member of Homeguard, a humanocentric hate group, and a former lover of Susan Ivanova.
History
Malcolm Biggs had a relationship with Susan Ivanova shortly after she became a full officer in Earthforce. It was passionate, but ultimately she broke it off after being reassigned to the transfer station on Io.
Eight years later, Biggs is a high-ranking member of the Homeguard, a radical anti-alien Earth organization. He comes to Babylon 5 where a number of Homeguard agents have been organizing random acts of violence against aliens. Biggs' ultimate plan is to assassinate the ambassadors of the four major alien powers on the station while other agents strike at their respective embassies on Earth. As soon as he comes aboard, he learns that Ivanova is stationed there. He takes her out on a date, hoping to perhaps rekindle their romance.
However, Security Chief Michael Garibaldi catches Biggs on tape trying to recruit a human into the Homeguard. Sinclair asks Ivanova to help them prove Biggs' guilt. She and Sinclair put on a ruse that he is secretly bitter and hateful towards aliens. Malcolm acts as Susan's escort to a diplomatic reception. At the reception, Sinclair makes makes a few pro-Earth comments to the discomfort of the guests. Sinclair and Ivanova continue the ruse in private, and Sinclair expresses his supposed deep discomfort with aliens. Biggs buys it completely. He outlines his plan and reveals the other Homeguard agents and a new stealth cloaking field. He then asks Sinclair to prove his loyalty by murdering an alien named Mila Shar. Sinclair and Ivanova reveal the double cross as Garibaldi and his team arrest Biggs and his men.
As he is being transferred to Earth, Biggs angrily confronts Ivanova, but her own quiet outrage is stronger and he falls silent.[1]
