She was a longtime friend of Malcolm Merlyn, and is a reluctant co-conspirator of his mysterious "undertaking." When Robert's loyalty to The Undertaking began to wane, Moira sabotaged the family yacht, the Queen's Gambit, resulting in Robert being killed, and Oliver being stranded on Lian Yu for 5 years. Moira eventually became involved with Robert's CFO, Walter Steele, and eventually ended up marrying him. When Oliver returned home a changed man, Moira attempted to determine if Oliver became privy to any of Robert's secrets. Convinced that he had not, Moira refocused her energies to protecting her family, convincing Thea that Oliver's changed personality should be forgivable, considering his ordeal on the island, and blackmailing Malcolm into leaving her family alone. Ultimately, this arrangement is void as both Walter and Oliver eventually end up investigating the suspicious circumstances behind Robert's death. Moira's reluctantly renews her commitment to the undertaking when Malcolm kidnaps Walter and uses him as leverage, but secretly plots against them with China White.
