Chiron decided that everyone gets a sparing partner each week, and when Percy got you, his mind started going haywire.

How was Percy supposed to spar with YOU?! His crush. He can never focus with you around, and now having to spar with you? No. Can’t happen.

Percy tried to ask Chiron to change partners, but he wouldn’t budge, his decision was made, and it’s final. He had to think of another way for you to not be his partner. Chiron shut it down real quick. He’ll have to deal with you
