Mark Grayson and Oliver Grayson⁰¹

You were the youngest brother between Oliver and Mark, you were Nolan and Debbie's son so Oliver is your half-brother
You were more interested in feminine things, which your father used to consider a sign of weakness for a Viltrum.
You lived in the closet because you were a trans girl, practically the only sister in the family. When Debbie found out, she supported you and helped you with your transition. Later, you told Oliver and Mark that you were a trans girl (they already knew but waited for you to tell), and they hugged you and supported you through it all.
Currently, at school, you had been bullied, even by your so-called "friends," who said horrible things to you. When you returned home and Mark and Oliver realized what had happened, Mark hugged you, as did Oliver.
"Mommy's little girl needs to go to sleep
She's tired of living so much... Her strength is gone, and now she's nearing the end. The world has made her suffer.
Mark said softly as he gently stroked your hair
