A recurring villain and an ally to the party were identical twins.

It seemed obvious to me. But I figured it’s a classic, and likely to briefly amuse them.

The party was great at ferreting out all kinds of mysteries. This would give them a quick mystery followed by a nice “spare my brother” moral dilemma to decide.

But the party did not give a shit.

The party blew right past a villainous monologue about “my brother” and similar movie tropes. They decided it was one dude with a personality disorder, and ignored all further information.

I had a big reveal planned, but it’s their world, and they had grudges against another villain so I promoted that villain to be more central to the plot. I finally fully sidelined the twins to focus on other NPCs that the party was more engaged with.

So they finished the entire campaign without figuring it out.

It’s no big deal, but still funny. I never know which NPC will resonate with the players and which won’t.
