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.

[second of awkward silence as the audio was removed but nothing was added back in and then it cuts to the next scene]
