A year or two prior to where I am in my camaign atm, I got one of the impossible to please clans (without a instructor, which I didn't have the parchment for at the time), where they have opposing traits which basically guarantees unfulfillable desires. Not only that, but the bastards started a feud after just 3 turns in the settlment, just when they were ready to go out being a lowly farmer, as was fitting for them. So I did the only thing I could, punish those bastards, turned them into explorers and sent them into the woods to die, which they did.

Now, one of my explorers mapping out the far corners of the world just found a ruin, and inside of it the banished clan who apparently survived starving to death, and somehow recruited them back into the tribe!

The only issue is that they still remember their feud and their anger, so back into the woods they go!

I don't know if this is a weird intended possibility, or just a bug or result of a limited variety of clans or something else, but it certainly is interesting!
