I remember your posts about it. It's just that much scarier actually seeing it in your own game.
Anyways, I wanted to see if a certain sim was an NPC or not. Turned out she was, because inviting her household over brought up the long list of service NPCs. I scrolled through out of curiosity until something extremely curious caught my eye:
Why, my fourth immortal is young again, and an NPC!
There was only one thing I could do.
I didn't get a screenshot of it, but Tegan found out that the other Tegan is also a childish Gemini. I think she's rather humble, though. Everyone else in Twinbrook is attracted to Tegan, but there wasn't a shred of narcissistic attraction between them.
They ended the day as good friends.
I'm at a stalemate in my dynasty due to having a full house, so I'm enjoying any mildly amusing and/or weird event when they come.
