IIRC, the name "Arret" for this planet originates in the James Blish novelizations, though I'm not sure if it was in the scripts he based them on, or if he made this one up himself. It's not spoken in dialogue in the actual episode, in any case. I don't currently have access to the Blish books; if someone else could confirm that, I'd appreciate it, because the article could use a note about the name's origin. --TimPendragon (talk) 00:02, March 28, 2020 (UTC)
