Griselda Gimpel#MurderbotTV This is obviously subjective, but my impression of Dr. Mensah from the books was 'made of stern stuff' (because, you know, planetary leader). TV Mensah, otoh, is more 'do it scared'.
Some of this is that we're not locked in Murderbot's POV for the series, and some of it is that they moved Dr. Mensah’s panic attacks to earlier in the narrative.
