In 3189, Ensign Sylvia Tilly thanked Captain Saru for a private meal with the bridge crew. Although the meal ended badly, Tilly believed it had a positive outcome. In her words, "Sir, we made a decision together, and we are living with it together. The fact that you reminded us of that and reminded us who we are to each other, that...I think that's leadership." (DIS: "Forget Me Not")
Later that year, the topic of leadership arose in another conversation between Tilly and Saru. He wanted her as his acting first officer until a permanent replacement could be found. During his attempt to persuade her into accepting the promotion, Saru said, "Part of leadership is the acknowledgement that one is suited to it." (DIS: "Unification III")
