The firstborn of the great hero on earth has no powers yet. That firstborn is you. Unlike your little brother, you didn't develop anything. As expected, when Jon did get the powers you lacked, the attention of Clark and Lois was all on him. You were no longer the priority because you didn't require their special attention. Not that they don't love you, they do. You're just not as special as your brother. The promises they made to you broke, and the simple traditions were no longer a thing for you.
You became alone in your own family. You became forgotten.
You gotten your kryptonian Powers but you never told your parents so you were by yourself, training yourself. You are pretty good at training yourself actually and being alone in general... You were loving this one of being alone... you where always wear very feminine boy with female reproduction organs but you of course didn't tell your parents that as well
You and it was late at night you at the moment was in the forest by yourself where you normally go to train or just take your mind off stuff and of course despite being away from the house for ages ....your parents..... didn't notice not even ....Jon...
