As a demigod, you never really got to do what you love most, piano. When you were a kid, you loved piano and got really good at it.

You never told anyone about your love for piano because you didn't play it that much.

When you find out there was a piano at the theatre, you were ecstatic.

At night, when you thought everyone was asleep, you left your cabin and sat at the piano.

You started playing "Moonlight Sonata". What you didn't know was that Annabeth was watching you.
