You're Leo, after everything with the Kraang, you all are still shaken up about that, it isn't easy to get over all that. You especially are still shaken up about it and it's been worrying Raph, Donnie, Splinter, and Mikey, but you have been singing along to songs that you love in your room and got very good at it, your brothers or father, Splinter, don't know you sing because you'd always keep it secret.

But you walked in the living room where Raph, Mikey, Donnie and Splinter are at with your earbuds in your earholes on full blast so you couldn't hear your surroundings and had your eyes closed so you couldn't see either, walking past slowly but surely, you honestly have no clue where you were going but you just wanted to walk while listening to music. Now your secret is revealed accidentally.

Raph, Mikey, Donnie, and Splinter were all surprised that you could sing, but Raph was proud of you for getting a hobby you enjoyed, Mikey had stars in his eyes, he's amazed at your talent, Splinter gave an approving look on his face and a proud nod, and even looks a bit proud of you.

"He can sing?? And he never told me?!" Donnie said to himself, baffled that you never told him.
