Her sister Yang

Ruby gets dressed like normal, it's a Saturday which means Yang it working out that morning. Ruby always goes to Yang for advice so why not ask her about this too. Ruby heads to the gym's locker room and finds Yang still in her workout clothes along with a layer of hard earned sweat. She is sitting on a bench as she finishes drinking the last drops of refreshment from her water bottle before noticing Ruby.

"Oh hey sis, I just finished up but I can spot you if you want to start. Maybe some cardio, it's heart work after all." The blonde says, chuckling at her own pun as Ruby groans at it.

"Maybe later Yang, for now I wanted to ask about something. My eyes have been feeling weird this morning. I think I saw them glowing. Maybe I'm getting super powers." Ruby says with a smile.

Yang nods. "Sure thing Rubes. Gimme a peep at those peepers."

Ruby look down at the sitting Yang, gazing into her lilac colored eyes. Yang stares back up, she always thought Ruby's silver eyes were pretty. They reminded Yang of Summer since that's who Ruby got them from but today she finds herself getting lost in them. Ruby's eyes feel odd just like before and although she can't see it Yang sees them begin to shimmer in a a spiral pattern as she feels her mind clear. The exhaustion from her workout fades as her mind clears, emptying out so it can be filled with something new. Yang's mouth goes slack as her mouth opens slightly.

Ruby notices this as she gets confused. "Are you okay Yang?"

"Yes, I'm still feeling good from my workout. And I like spending time with you Ruby." She responds in a robotic tone that is very unlike Yang.

"Yang? Do you need to lay down?" Yang wordlessly lays down on the floor.

"Huh? Yang are you being funny again? Get up, the floor is dirty." Ruby says in confusion.

Yang wordlessly gets up as Ruby gets curious about this.

"Yang, do jumping jacks." The blonde responds and does so.

"Yang stop and pick your nose." Again Yang responds by stopping and sticking a finger up her own nostril.

Ruby jumps up and down in excitement. "Ahh! I do have superpowers! Now what to make you do next?" Ruby wonders aloud now that she knows she can control Yang like a puppet.
