"So, who is it going to be?" Billie asked.
"Obviously me," Dean said.
"Now wait a minute," Sam countered, "It should be me."
"Sam, don't be stupid. It's my job to protect you."
"I'm an adult, dean. And I'm the bigger screw up."
"You're the brains of the outfit, I'm just a grunt."
Sam rolled his eyes. "You're way smarter than me. especially when it comes to figuring out patterns."
"Well, you're a giant, so you should live?"
"What?" Sam asked in that annoying high-pitched way of his.
"Enough," Billie said. "If you don't choose, I will."
"Kill me," they both said in unison.
"Fine," Billie said, and dispensed with both of them.
"Where are we?" Dean asked.
"The Big Empty, I guess," Sam answered. "That's where Billie told me she would send me next time I died."
"So, it's just the two of us here forever?"
"Yep."
"What do you think will happen if one of us dies here?" Dean asked.
"Why would we die here?"
"Just the two of us, forever, no other distractions? Oh, don't worry, I'll kill you eventually."
"Or, I'll kill you," Sam smirked.
"We'll see," Dean said.
