By age 10 Gabe knew that his parents love his dead older sister more then they loved him. At least, that's the way he felt. He never said anything though. He didn't say anything until one day when he just couldn't take it anymore. He stormed upstairs to his room.
Diana, his mother knocked on the door.
"Honey?"
Reluctantly he opened the door.
"Gabe what's wrong?"
"SHE'S SUPERGIRL and I'M THE INVISABLE BOY! YOU LOVE HER MORE THEN YOU LOVE ME"
"Gabe that's not true," Diana told her son, "when we lost her it was the worst thing in the world for us. I thought I was going to drown in my sadness. Then you came along"
"THEN WHY DO YOU HAVE MORE PICTURES OF HER THEN YOU HAVE OF ME!"
Diana knelt down beside him and stroked the boy's hair.
Supergirl and invisible boy
"It's because she's not here. All I have left of her are memories and pictures. You on the other hand I have right here"
"I wish I could have known her," Gabe said snuggling in his mothers arms. Suddenly he didn't feel like the invisible boy anymore
