If it's in italics, it's a flashback to when Seth betrayed The Shield.  This takes place at Money in the Bank.

True Friends - Bring Me The Horizon

"There's always a Plan B."

"He's done it! Dean Ambrose has the contract!" JBL exclaimed.

"Dean Ambrose has won Money in the Bank!" Michael Cole yelled.

Dean remained on top of the ladder, looking down at the other competitors in the match. Each of them deserved the briefcase, the chance to win the title, but Dean knew he deserved it more.

After getting off the ladder and leaving the ring, he headed backstage. He expected to be met by Renee or JoJo (personally, he preferred Renee for obvious reasons), but instead, the man challenging Roman Reigns for the WWE World Heavyweight Championship later that night stood in front of him and blocked his path.

Dean stared at Triple H, confused, as nothing had happened after informing them of a "Plan B."

The sound of metal hitting muscle caused Dean to whip his head around. Seth had just hit Roman in the back with the chair he had gotten earlier. Dean was in shock, and it was evident on his face. Seth looked from Roman to Dean and smirked.

Before Dean could react, Seth had hit him with the chair, too.

"What do you want?" Dean frowned.

"You won the briefcase, huh?" Seth asked, smirking. Dean said nothing. "You plan on cashing in tonight?"

"No."

Seth raised his eyebrows in surprise. "Really?"

"Yeah," Dean replied. "I wouldn't cash in on Roman like that. He's like a brother; I'd warn him first."

"What if Roman doesn't win?"

"Well, he's facing you," Dean pointed out. "So, I don't have to worry about that, do I?"

Seth frowned, just as Dean spotted Renee down the hall. He walked away.

"I didn't sell out; I bought in."

After his interview with Renee, Dean left to his locker room.

A match had just ended, and soon, Roman and Seth had walked out. The Lunatic Fringe had no doubt in his mind that Roman would retain his championship, but he stayed seated and watched anyway.

At one point, Seth had done the exact move that put him out of action for 7 months, and Roman actually made sure he landed safely.

Dean wished that Seth was still injured, so he didn't have to see his horrible face backstage every night. So he wasn't reminded of his betrayal every time he stepped in the ring with him.

When Seth pinned Roman, got the 3 count, and won, Dean didn't even have to think twice. He grabbed his briefcase and stormed out of the room to Gorilla.

He didn't even bother telling them to play his music. He marched down the ramp, slid into the ring, and hit Seth with his briefcase. As Seth landed on the mat, Dean handed the ref the briefcase, cashing it in.

After hitting Seth with the Dirty Deeds, he pinned him.

"1...2...3!"

Before getting up, Dean whispered, "This is your own fault."

"The winner, and the new WWE World Heavyweight Champion: Dean Ambrose!"

"You got a lot of nerve, but not a lot of spine. You made your bed when you worried about mine. This ends now."
