Anyone considered maybe using some fragments of the dialogue during flashbacks? There’s a one nice line that would work well with the final showdown (Anakin asks Obi-wan what would he do if Anakin failed him as well, and Obi-Wan replies that Anakin would never fail him). I think it’d work super well with the “I’m not your failure Obi-Wan” moment).
