"...Do you hear that?" Nos asked just above a whisper.
Two looked up from her book, keeping still to listen. They were in Nos's study when the sound of distant piano playing drifted down through the halls. It came from the tower.
"Could Fletcher be practicing?" Two wondered.
Nos stood up and hovered out to the library, Two following just behind him. They reached the doors to the hall and turned right, coming to the entrance at the base of the tower. Two followed Nos's lead, masking her signal and flying straight up the middle of the spiral staircase. They stopped at the trap door.
There was no question about it now ‒ Fletcher was playing. He stumbled and repeated himself, meticulously perfecting a few bars under tempo before going back and starting from the beginning. Nos and Two looked at each other, smiling. Two reached out and knocked on the wooden trap door before easing it open.
"Oh ‒ Mom!" Fletcher bolted from the stool. Nos popped up behind Two. An egg carton filled with dirt sprouted tiny bean plants on the windowsill behind the piano.
"Sorry, sorry, we didn't mean to startle you! You're doing so well!"
"Oh, uh... thanks," Fletcher warbled.
"So what were you practicing? Is it something from one of your video games, or did you just run out of other things to do?" Nos smirked.
"Hey, come on! It's an experiment! If plants are supposed to like listening to classical music, I thought they might appreciate a live performance even more."
