I did what I had to do
A/N: Part two of Here’s what we’re gonna do
Dean x Sister!Reader Sam x Sister!Reader
“We must get your sister as well.” Cas said as he looked at Sam and Dean, “She is the back up plan for both angels and demons. If either of them get to her first and she says yes then all of this is for nothing.”
Sam and Dean shared a confused look, “What are you talking about Cas?” Sam questioned.
“Our sister’s been dead for almost thirteen years.” Dean added gruffly. He hated talking about you. You were his twin, the one he could have saved if he had been there to intervene in the fight you had with John. Instead he was at the library and you went searching for him. You never found him. Instead you had been taken by a shifter and killed.
It was his fault.
“No she has not.” Cas replied with a confused face, “She resides in Columbus, Ohio. I believe she works at a bank.”
“A bank?” Dean deadpanned.
“Yes, I believe so.” Cas responded.
“Cas,” Sam said before letting out a breath, “Our sister died when she was seventeen.”
“No she did not.” Cas argued back, getting annoyed that the boys didn’t believe him.
“I’m warning you Cas, drop it.” Dean huffed out.
“Fine. I’ll show you.” Cas responded before placing his hands on each Winchester’s shoulder’s and zapping them to your location.
