 Billings saw Weaver as a seeker. In the late 1950s, he joined a religious group called Self-Realization Fellowship, started by a well-known yogi. He stayed in it the rest of his life. Billings says Weaver had an inner peace she believes helped him smooth over disagreements on TV sets and create a sense of family with fellow cast members. Activism was important to him, and he would give talks about the environment on college campuses.
