I grew up *here*, Stefan, with you, with Sebastian, with Mom and Dad. I'm a Rathbone. I have always been a Rathbone. I don't know how to be anything else."

"I was a *newborn*," she said. "I was barely a few hours old. Whatever happened in that hospital - that wasn't *me*. I didn't switch the babies. I was a *baby*."
"That's true."
She looked up.
"What?"
"That part is true." Stefan's voice had not changed. "You didn't choose any of it. You had no agency in what happened in 2003."
"Then-"
"But you had agency in everything that came after."
She went silent.
"Sienna." Stefan
