Tobias: You like to sing. Actually, you love to sing and you're quite good at it. Tobias sometimes walks in on you and watches you sing. You think no one knows about your talent, but Tobias knows, and he loves it.
Eric: You love to write about your experiences. Especially about being Dauntless or loving someone like Eric. He doesn't know, but does have suspicions since you stay up very late to write.
Caleb: From a young age, you have played the piano immaculately. Erudite was quick to make sure your talent wasn't wasted. They make sure your piano is always in top shape. Caleb doesn't know, but you would like him to.
Peter: Being Amity, you are very happy all the time. Normally, you don't know you're dancing, it just happens. You let your body take control and just let it happen. Peter sometimes catches you, but never says anything. He just watches and smiles at how perfect you are.
Uriah: Your talent isn't hidden. Everyone you know and more, know you're really good at acting. Your friend writes plays for you, and you act them all out. You can be very dramatic and Uriah loves it.
