Sam stood, mouth agape, and speechless…

The fight with Abaddon resulted in her escape, again, but before she left, she knew how to best break the Winchesters—from within.

Just plant the seed, Abby, let hate fester all on its own and watch it implode. I LOVE bunker busters…

"He didn't tell you. I knew before you did." She smiled and bared her teeth in a snarl that would be burned into Sam's psyche for at least the next 2 hours, or at least until he focused his anger on his older brother. She walked confident, cocky circles around Sam, looking him up and down and wondering what it would be like to swim around in there. "I can't possess you—well, I could, but I won't—I prefer your brother. But he let someone inside you."

Sam looked confused. Dean was pinned against a pillar in the church, bleeding and near unconscious, and Ezekiel was outside, unable to enter the church due to the sigils painted on the outside. Abaddon thought this through…

It would take little work, she thought, to watch them disintegrate; to turn on each other, to completely sweep one away in a tide of anger and watch the other skin himself alive….

She had it all set up…kidnap a few more hunters, make a phone call, set up a trap…ever since she learned of Dean's little angelic switcheroo with the celestial memory wipe, she gained a foothold and would use it to her advantage.

Of course, because the Winchesters were involved, the fight yielded casualties, but she didn't care. All the demons who responded to her invite were dead, as were all four captive hunters. She'd beat Dean just within an inch of his life—as soon as she dropped her bomb, she'd make her way out and let Ezekiel in, but he'd be too busy fixing Dean to pay attention to her escape route.

"You've been an angel puppet, Sam."

Sam stared at her and clenched his jaw, planning how to take her out as soon as he could.

"And not only have you been a puppet, your memory of it was whitewashed-."

"Shut up," Sam growled.

"And guess who planned it all? When you were dying? When you told DEATH you were ready? You're ever-faithful, ever-loving, dedicated-only-to-you brother."

Sam was silent, then quick, flashing glimpses of Bobby (Bobby?), a cabin in the woods (where was that?), Death (Well played, my boy…)played like old movie frames in his mind…

He felt the submission, he felt the cold, he felt the relief of Death, knowing that no one would ever get hurt because of him ever again. He was ready to go—he even said so. Then Dean showed up. Wait—not Dean?

Abaddon saw the recognition in his eyes, and fanned the flame. "Really"? Did you think your brother really killed three demons in that store? Oh, Sam…it wasn't your almighty protector! It was YOU—well, wait—it was NOT you, it was Ezekiel…you know your friend outside? The one you met that Dean pretended he didn't know? He's been possessing you since Dean got you to the hospital after you didn't have the balls to complete the trials. You were DEAD, Sam. You were burned from the inside—does that sound familiar? No one could save you—so big brother stepped in, oh, wait—no he didn't." She laughed, then she continued. "He wanted you to live when you didn't even want to, so he invited an angel to hitch a ride and heal you in the process. Best part is, he didn't want you to remember, but that angel knows everything about you. He swam in your head, Sam, without your permission."

Sam lost his breath. As Abaddon continued, his memories flooded back.

"Oh, Sam," she feigned sympathy. "You're such an ass. Your brother made a fool out of you. He lied to you—about you!"

Dean heard everything the fallen angel was saying. He saw his brother's shoulders sink. He saw the recollection in Sam's face. This time, when the wall fell, there were no seizures, no screaming…it was just blood draining from his brother's face.

"Have fun with that, honey. See you soon, Dean."

With that, she disappeared, and Dean slid down the pillar and fell into a heap on the floor.

Sam made no move towards his brother.

The elder Winchester stood, on shaky legs, and reached for Sam for support, who passed by him towards the exit. He didn't stop.

Nor did Sam acknowledge Ezekiel as he walked to the car.

It was going to be a long ride home.
