Charles Widmore
In 1974, Richard entered the Dharma Initiative's barracks in "LaFleur" and demanded the whereabouts of two members of his people, they having been killed and buried by Juliet Burke (Elizabeth Mitchell) and James "Sawyer" Ford (Josh Holloway) following Locke's successful attempt to stop the time skips. Sawyer managed to appease Richard by taking responsibility and revealing knowledge of Alpert's encounter with Locke in the 1950s. In 1977, Richard again encountered Sawyer in the jungle in "Whatever Happened, Happened", this time with Kate Austen (Evangeline Lilly) and a wounded Ben Linus, whom they wanted healed. He warned Sawyer and Kate by saving Ben's life, Ben won't retain any memory of the event and will lose his innocence. Sawyer and Kate acknowledged this and Richard took Ben to the temple. Shortly after this exchange, Alpert tells several of the Others he did not answer to Charles Widmore or to Ellie (Alice Evans), then leader of the Others. Regardless, he was briefly berated by a middle-aged Charles Widmore (David S. Lee) in "Dead is Dead" for bringing Ben to the camp.
