“Ordinarily, I wouldn’t even think before salting a leech. But, since you had the decency to ask first instead of going right for it, you can go ahead and have your fill.”
Also, “fun” fact about leeches IRL, they have three mouths with a hundred teeth in each, but you can’t feel them because their saliva is a natural anaesthetic.
