The cut that Georgiou inflicted on Captain Burnham's throat in Terra Firma, Part 1 (2020) has disappeared.
At the end of Terra Firma, Part 1 (2020), Emperor Georgiou ordered that Captain Burnham be taken to an agonizer booth. Here, Burnham is taken to a holding cell and only put into a booth when Georgiou so orders again.
Georgiou can be seen with her left arm crossed over her right wrist when the Guardian of Forever is talking about his true location. Then when the camera angle changes her left hand is down at her side and her right hand is holding the knife on her waist.
Mirror Saru says he can feel Vahar'ai coming on. In An Obol for Charon (2019), the prime timeline Saru didn't undergo Vahar'ai until well after this time period, and then only because proximity to the Sphere artificially induced an early Vahar'ai. He was expected to live for many more years before reaching Vahar'ai otherwise, so mirror Saru, who never encountered the Sphere, should also have gone many more years without undergoing the change.
