Sam pushed away quickly, nearly knocking Gabriel to the floor. "What the hell?!"
"I told you, I-"
"Yeah, I get it!" Sam screamed, "So, so what... you just kidnapped me to tell me this!? You messed with Dean's head. You- You're really sick."
Gabriel took a shaky breath. Sam had called him... sick? He clutched at the bottom hem of his jacket violently. Sam walked around him and toward the door briskly, "I'm going back. Don't follow me." Gabriel gritted his teeth.
"Stop Sam." He turned, facing the Winchester, "Don't leave."
Sam frowned, "You can't just kidnap someone and tell them you like them, then expect everything to be fine. The world doesn't work that way." he groaned.
Gabriel coked up a little, "But, I thought-"
"Look..." Sam firmly placed his hands on Gabriel's shoulders, "I'm glad you told me, but this is not the way you go about things. I need to get back-"
"No!" Gabriel screamed, sending Sam back a bit, "No! You can't just leave!"
"Gabr-"
Gabriel used his power to slam Sam hard against the back wall, knocking the wind from his lungs. Sam gritted his teeth as he fought the force best he could. "You can't just leave! They said you'd stay if I was powerful!" he cried. "They said you'd love me!"
Sam was struggling to breathe, "Gabe-"
"No! You can't leave! I- I'm powerful now! I defeated Cas! I'm strong now!" he started crying, it wasn't something a powerful angel- no, not angel. Gabriel didn't really know what he was anymore. "Sam..."
The force holding Sam to the wall loosened. "Sam..." he pleaded, his eyes swelling up with tears.
He walked over to the wall before releasing Sam entirely. He grabbed onto the Winchester, desperately clinging as tears trickled down his cheek. Sam didn't have the faintest idea what was happening, but he'd never seen Gabriel looking like that, crying and helpless. So he just hugged back. He held the angel in his arms as he cried. "Gabe... what happened to you? Tell me everything. You'll be okay."
"I promise."
