It is very rewarding to watch Good Omens when you are partnered to a historian, by the way.
Back in July we were sitting and rewatching season 1 together, you know, pre-gaming for season 2, and it's episode 3 and the Rome scene comes on.
The partner reads from the screen, "8 years later," which is to say (he thinks out loud) 8 years after the crucifixion. 41 AD.
And then he goes, "Oh! Caligula! I wonder if that's who Crowley was tempting?"
And in the next episode-- "Aziraphale has a bust of Nero in his shop! Did he know Nero in the book?"
After season 2 and my subsequent brain-melting, I now own the scriptbook, and know what you all know, too: yes, he WAS there to tempt Caligula (and he Did Not Care For It), and yes, Aziraphale DID know Nero. He was his music tutor!
I have no larger point here, I'm just very proud of and impressed by the partner, all the time. Imagine not even needing the scriptbook to suss that out. Imagine just knowing who was relevant in 41 AD OFF THE TOP OF YOUR HEAD.
