In true Discovery fashion, Burnham tries to get to the bottom of Sarek’s hidden memory, but he literally fights her to protect the memory, with the two having a showdown using Suus Mahna, a Vulcan form of martial arts. The onscreen combat has great choreography and feels very visceral, and this is a miracle because the two actors never had a chance to rehearse together before filming the scene. Burnham actor Sonequa Martin-Green was comfortable winging it because she had extensive stage combat experience, but she and the crew were surprised to discover that Sarek actor James Frain had no such experience.
