The set-up for Romana leaving feels a little abrupt. (She makes a comment to Adric about her and the Doctor going their separate ways upon returning to N-Space) Though I get that she doesn't want to return to Gallifrey.
Ah, okay. I've heard one Gallifrey audio (I think she was Lord President in that? Not sure; Leela was also involved), though the audio wasn't as interesting as I thought based on the premise so I haven't looked much deeper into the Gallifrey-centric ones.
Starting episode 4. I thought the lion people were supposed to be sympathetic since they were enslaved by humans, but they're also abusive bigoted slave-owners.
I liked Romana's ending better than I did at first, though given how annoyed 4 was with Adric, I feel like this particular TARDIS team isn't going to go well haha.
