Just a Girl
In another world, she is a girl. Just that. A girl. That's not to say she isn't brilliant. She definitely is, with her intelligence and beauty and grace. Her personality shines.
In this other world, though, she is not a weapon. Her mind is not filled with other people's secrets. Dangerous secrets.
She's just a girl, intact, with her own mind and her own iron will.
She is not broken. She is complete and she has an impressive life ahead of her that doesn't involve Reavers and Alliance experiments on her brain.
In another world, River is normal. She's happy.
