Rant about something Spyfall-related but not the episode itself (Doctor Who)

Okay, I've now watched both parts of Spyfall, ie. the first S12 Doctor Who story. I'm going to post some first thoughts soon, but I'm now going to rant about the fact that the official PR of the show managed to spoil me for a major twist though fandom and such didn't. So this isn't actually about the episode, but will contain a major spoiler.

It also, uh, contains a lot of ranting. And swears.

( Here be SPOILERS for anyone who hasn't yet seen Spyfall parts 1 and 2 )

An actual Spyfall thoughts/reactions post, with spoilers

Okay, here are some initial thoughts actually about Spyfall parts 1 and 2 before I crash into bed. So, spoilers ahead for the two newest Doctor Who episodes. Nothing super analytical, but what comes to my mind first. This was supposed to be brief, but surprise surprise, it wasn't.
