Chapter 5- Final Chapter!

A flicker of fear passed Lucifer's face before Michael/Dean lunged. Gabriel/Sam pulled the demons off of the gravely injured angel, his brow crinkled in concern. Castiel looked up at Sam/Gabriel feeling only relief.

"Brother." Castiel rasped, not quite sure who he was talking to. Castiel slowly pulled his mangled wings to his side with a wince before pulling himself up with the offered arm. Gabriel/Sam gently ran a hand over Castiel's wings, temporarily patching them up.

"Cas, why did you come here?" Sam scolded, smoothing the ruffled, crooked feathers.

Castiel rolled his eyes. "It's a Winchester thing, Right? Jumping into a battle you don't expect to win?"

Sam laughed before spreading spectacular silver and brown wings. Together the Archangel and the smaller angel pulled each other up, Sam's wings helping Castiel gain altitude. Above them, Lucifer and Dean were tangled together, a new ferocious twist to their fight. Water was pouring from the sky, several inches filling the craters and fault lines around them.

Dean split off from Lucifer to fly next to his brother, his eyes glowing with Grace and adrenaline. "Heya, Sammy!"

The two Archangels and Castiel soared up and up before they swept around the Devil. A new spin to the fight had demons swooping around them. Dean almost found it funny, how quickly it was over after that. Castiel fought off the demons, Sam as a distraction and Dean went behind the Devil and plunged the Archangel blade straight through Lucifer's chest. Lucifer crashed to the ground once more. Brilliant wings burnt into the ground around him. The demons shrieked and disappeared. The ground quieted and the storms slowed. Sam turned to Dean, silver and gold feathers brushing together. Castiel panted next to them, Lucifer's dead body far below.

"We did it." Sam's voice shook. The three brothers beamed at each other, then Dean groaned suddenly.

"We had a deal! No!" Dean shouted, shaking his head. Gabriel snatched control of Sam, forcing him back and grabbing Castiel's arm. Dean stiffened…but no that wasn't Dean.

"Michael." Gabriel hissed, using Sam's mouth.

Michael gazed around for a moment before smirking at Sam/Gabriel and Castiel. "Thanks for the suit."

Then without another word, he disappeared. Castiel and Sam/Gabriel turned to each other, horrified.

"No! DEAN!" Castiel cried out, his wings flapping harder than they should, with his injuries. Gabriel pulled Castiel to him and listened as Sam screamed in his head and Castiel screamed in his arms.
