Like I’m talking as a side thing when he was younger and no one was looking. He was going to impress his brothers with it because he’s always craving for their attention. So for once instead of doing something big and flashy like learning a new skateboard trick. Leon just happened to over hear donnie talking to Mikey while they were watching a young piano prodigie, how difficult it was to learn and master the piano. So Leon decided he’d master it in a month to impress them. He used to go to this little street where there was a piano for public use and practice there. The piano was completely out of tune, but that didn’t matter to him he just needed it to practice where to place his fingers and such. Finally he figured out how to do it and he was able to learn how to read the notes, and play a single song! In a month!! He was very determined and ready to impress his brothers, but he once again heard them all talking. This time however they where watching a movie and complaining about the commercials, which so happened to be a piano player. The piano player was trying to sell tickets to their show via phone call, and the brothers were complaining that piano wasn’t “even all that”. (It was out of spite because they where missing their show that’s it) leo was a little upset that he just wasted a month, but he realised he actually really did enjoy playing the piano from time to time. So whenever he was stressed, upset, angry, or bored he’d go up to the surface to the public piano and practice.
Years later during a mission to get into a fancy party thrown by big mama they need a distraction. When conveniently Leon over heard some waiters talking about how the pianist still hasn’t arrived. Leon, who luckily wore a suit for this mission, stood up and started walking away from threat hiding position. All of his brothers tried to reach for him but to no arrival. Leon walked straight to the stage, jumped on top of it and sat down on the bench. He stretched out his arms and closed his eyes, before placing a beautiful melody. His brothers were pretty shook
