Around Christmas time, the Aphrodite cabin would always put a little too much mistletoe around the camp. They loved watching the other campers blush and would get extremely violent if they refused to kiss.
But one day, Percy and Clarisse ended up walking under a piece in a doorway. They both looked at each other angrily, and unfortunately, there were Aphrodite campers around.
They didn't kiss, but the Aphrodite kids had only stopped insisting after a massive fistfight quickly turned into full out war against the cabin ten
Chiron had had to physically pull Clarisse away from using Percy as a punching bag. That had also been the last time he'd allowed mistletoe in the camp.
