I'm really sure you are.

A note. This is not canon to anything in the Kid cosmic universe. You can choose to be an older or younger sibling.

*. . . Your brother. He's found some different rocks. He'd glued them to hex nuts without a second thought. For "Cooler" purposes he says. *

later you heard of him getting in trouble at Flo's Cafe,

she really didn't get any visitors other than Carla, Carlos, and Carl. They just got coffee.

Anyway. You sleep with him. Since Papa G has no room in his House. You all live at a Junkyard. It's fine otherwise. You can find little things in piles to make stuff. Like Kid did a long time ago. He made a bike with Papa G, and named it Spitfire.

Anyway, you're sitting in the Trailer/Camper where you practically both live. Reading some of the comics he has. [There's so many.] When he suddenly bursts in, with a confident tone-

"BROTHER/SISTER! Come! I wanna show the world the cool powers of the STONES!"

"And you will be with me so you can hold the recorder thingy..! If anything goes Wrong of course!"

and now here you are. Holding a camera. Waiting for him to be ready. Your hands are shaky, so this might not do well.
