Sam wakes up to find Billie sitting next to his bed, one leg over the other, in a chair he distinctly remembers as the one Dean uses when he wants to watch over Sam after a particularly bad scare.
“Hello, Sam,” she says, calm and serene as always.
“Um, hello,” Sam says, sitting up, and then, “No offence, but why are you here?”
She smiles at that, leaning forward just a little. “What do you think?” she asks simply.
Sam frowns. “I’m – dead?” he guesses, and then immediately backtracks. “But I can’t be, I’m–”
“And yet,” she interrupts. “You are.”
“You’re here to reap me?”
“I already have,” she tells him. “You’re in Heaven.”
“Heaven?” Sam’s frown deepens. “I thought you said–”
“And yet,” she repeats, and she is still smiling. “Here you are.”
