I thought this was AI when I saw this, I have watched Macra Terror but it’s been a while and I can’t remember him saying it that’s the problem I have with Classic Who I can never remember what happened after a year of two, Planet of the daleks was my first Classic who episode and I can’t remember a thing from when I watched it in 2021. I went on BBC iPlayer and it was there though I’m surprised BBC didn’t bleep it out.
