Jeff entered his room to find his older brother staring with intense confusion at his computer and froze... as he entered the young man looked up and asked "Who am I... Who was I?" and Jeff grinned maliciously.
He used to be Jeff's bully, he used to be Jeff's idol, he used to be the golden child of the family, but now he was reduced to an intent-less placeholder that could fill any role and had no will of their own... Though he had the cognitive ability to use the Chronivac at any time, the lack of desire for any specific outcome prevented those effected by it from actually setting anything up. Usually left staring at the screen or sitting nearby waiting for the user. People other than the user forget they exist and ignore their presence... its great for transformations when a power dynamic is at play.
"It doesn't matter. What matters is who you are going to be." Jeff said shooing the 20 year old away from the computer as he closed his bedroom door and approached. "Do you have any preferences?" Jeff asked simply testing the completeness of the placeholder package he found and applied.
The young man, formerly Derrick, scrunched his nose in thought. "I.. I want to be somebody..."
Jeff liked the confusion and lack of direction Derrick had but couldn't resist the urge to really drive it home... "I could make you my sex slave, you'd be female but die if you don't suck my balls or cock at least 4 times a week and it would be an excruciating death for you. I could make you my great grandpa with about 1.5 months left, you'd wet yourself everyday and be in an old person's home for the last meaningless fraction of your life. I can make you a female chipmunk and release you outside. Your last option is a homeless drug addict my dad's age, struggling to pull the shattered remnants of his life together. Which do you want?"
Derrick thought, "Wow, all of those sound like well rounded identities with relationships and a place in the world, I'd like any of them, can you pick for me?"
Jeff barely stifled a giggle. "Yeah, take a seat..." he motioned to the bed and began implementing the rest of his plan for his former brother.
