The original scene goes as follows
Sam: It's just... sometimes the world can be a scary place. It's hard to know who's dangerous or not.
Nightshade: Hmm, that's true, though dissapointing.
Sam: Hey, it's ok. I know I'm safe when I'm with my friends or other non-binary people.
Nightshade: Non-binary?
Sam: People who aren't female or male. Oh I'm sorry, I shouldn't have assumed.
Nightshade: I always felt my pronouns felt right, but what a wonderful word for a wonderful experience.
the one on BBC iplayer goes like this:
Sam: It's just... sometimes the world can be a scary place. It's hard to know who's dangerous or not.
Nightshade: Hmm, that's true, though dissapointing.
Sam: Hey, it's ok. I know I'm safe when I'm with my friends.
