'How could he? I almost told him….. No. He's not going to tear me apart. I'm a fucking angel of the lord. He's just a human he doesn't matter. But… he did this to me. Even if it was just a ripple of an emotion, he hurt me. It's my turn.' Gabriel thought as theaters stopped. He knew what he was going to do. Sam cheated on him. He was going to get his revenge. That blonde bitch meant nothing. She wasn't his friend, she was just something that he could snap in half with a thought. He needed someone with an emotional place in Sam. Then he realized it. Dean.
"Dean" he moaned out as the door opened, and Sam froze. There were two people moaning on the bed. One a human, and one an angel. It would be normal for him to walk in on something like that before – it wasn't the first time he'd come home early – but it wasn't the angel with black hair on the bed with his brother. It was his angel, his boyfriend Gabriel. He was laying on his back, Dean moving himself up and down on the angel's cock. Dean hadn't noticed him coming home.
Gabriel opened his eyes as Sam walked in. Sam dropped the bag, but when Gabriel looked over, he wasn't surprised or shocked. He flashed his usual trickster smile, and Sam felt tears rolling down his cheeks. He opened his mouth, but there was just a silent sob, and he turned around and walked out closing the door silently. There was nothing that mattered anymore. If he did something to make Gabriel cheat like that, he couldn't remember it. He'd been depressed for a few months, but he'd been able to hide it from everyone, including his angel. 'No' he thought 'Not my angel anymore.'
He hot-wired a car and went to Walmart, knowing he could get everything he needed. He bought a bottle of bleach and a pack of razors. Gabriel couldn't stop him. He had no idea how long Dean and Gabriel had been together. He got a new tattoo over his ribs. The enochian writing to hide him from all angels. Gabriel had modified his old ones, so he made sure he couldn't be found. Everything he ever ad was lost. His love for his only remaining family remember, his boyfriend, his chance at happiness, and every thought about it getting better. He was going to end it all.
