I thought Una’s encouragement for the Knight during the fight with Error was very interesting. As he is getting beat, she yells, “Now now Sir knight, she what ye bee, Add faith unto your force, and be not faint (1.1.19.164-165)”. Because of her strong warnings against his entering the den, it would be easy for her to have made certain that he knew she was right. She does come close to saying this, but in a more encouraging way. It comes across more as, “You said you could handle it, and I know you can. Now prove it.” This shows the strong unwavering support she has for the Knight during this episode.
