In "Bygones", Weaver was stunned when she realized a lonely young woman murdered her roommate because of unrequited love. She then reconciled with Lopez and the two of them made their first social appearance at an impromptu drinking party after Mark Greene died. Weaver was visibly saddened by Greene's death and broke down after hearing the news of his passing. She later told Sandy she knew his demise was coming but never thought it would affect her as deeply as it did. She realized she had lost a friend and regretted the years they spent in competition for various ER posts and promotions.
