"We should probably kill it "

Lae'zel has been trained since birth to kill ghaik and their spawn.

It ends up dead, very quickly.

The parasites in their heads shift uncomfortably.

"It was going to die or it was going to kill someone. This way has the fewest deaths and the least suffering. It wasn't having a good life," he explains to someone. Mostly himself.

"It really was. It's a sad fate, to be born mindflayer spawn."

Lae'zel sheathes her sword. "It's a sadder fate to become one. We should keep moving."

... ... ... WHO THE FUCK IS RUNNING A TEAHOUSE IN THE WASTES FULL OF MONSTERS?

"Maybe it was less full of monsters and then they never moved?"

"They should have moved! There aren't any defenses there! That's a teahouse!"

"Maybe those sheep are secretly trained attack sheep."

"...I don't think those are a thing?"

Cayden goes to investigate the archmage or ninth-circle cleric that is running that teashop.

The tea shop is surrounded by coastal wetlands, bright and picturesque and smelling of salt. 

Inside is an old human woman at a table  with a younger, pregnant woman. "Now, eat up, pet--" says the older woman. She hears the party come in. "Ah, customers! What are you coming to visit ol' Auntie Ethel for?"

"Good morning, ma'am. I have a mindflayer tadpole in my brain and I was wondering if you knew anything about how to fix that."

"Oh, I know just the thing! We would need to discuss payment first though, love. My expertise doesn't come cheap." 

See! Archmage or ninth-circle cleric or something! He knew it!

"Of course, ma'am. What kind of payment are you thinking of?"

(The pregnant woman has stopped eating now Ethel isn't watching her.)

"When you get to my age, money stops being worth the effort. All I want is something you'd have to give anyway to get the tadpole out: just one eye."

"Mhhm," Shadowheart hums doubtfully.

"I do not think I have to say this, but I would advise you to not," Gale says quietly to him. 

"...what are you going to do with my eye, ma'am?"

"I'm afraid that's my business, petal. Don't worry, it's nothing nefarious. I'll pluck it out, kiss it for luck, and pop it right back in. You won't even have time to miss it."

"...could I trade two eyes for two different people who aren't me not having a mind flayer anymore, is there some other body part you're interested in that I could trade for a third person, and is this a right-now offer or could I come back later after I've checked if there's a different way to get the mind flayers out?"

"Are you trying to be the first person who dies of generosity?"

"Oh, you can certainly shop around if you want to, though you're not going to find anyone else to help before you change." She stops and thinks for a bit, a finger tapping on her chin. "I'll say one eye per parasite, preferably from the person who's parasite you want removed."

"Nope. My eyes. Can I get two people if I give you both of them?"
