Castiel and Clint Down: 2013

Natasha looks through the gaps in the guards' legs - Clint was gone too. Satisfied Castiel had taken him somewhere safe, she focused in for the first time since entering the nest. She slowed her breathing, adjusted her grip on the blade, and prepared to do what she did best. Kill.

********

The team were ready to go. Tony, Steve, Sam and Dean we're heading out the door when Castiel dropped into the centre of the room, crouched over Clint's dead body.

Tony turned around shocked. "Barton!? Hey!" He ran over, kneeling at his side.

Sam looked to Castiel. "What happened? Where's Nat?"

Castiel, out of breath, sat back on the floor gathering his words. "Tekin... He mixed his blood into Barton's... Stabbed him first... I-"

Castiel stopped, he fell onto his back.

"Hey!" Dean ran over. He looked down and saw blood beginning to leak through his coat. "Shit! He's been hit!" Dean pulled the coat open and lifted Castiel's torn shirt up, several deep wounds across his stomach were leaking blood.

"I thought he couldn't get hurt?" Steve said, helpless and confused.

"Not if it's supernatural - there must be some... uh... maybe vampire blood, but he'd be... I don't know, this doesn't make sense." Sam was panicking.

Dean composed himself, pushing the bloodied coat onto the wounds to stop the bleeding. "We've got a problem. If Clint wasn't dead when the blood mixed, he's gonna be a vampire very soon."

"And if he wasn't?" Tony looked at Dean.

"Then if we can't save Cas, he ain't coming back." Dean took the coat off Castiel's wounds, examining them up close. "Cas has the blood, it isn't going to be long before he turns. We don't know how either of them will be when they turn and wake up... How hungry they'll be."

"Where's Nat?" Sam looked at the mess in front of him.

"I have no idea." Dean bit his lip and closed his eyes. "Okay. I'm taking charge." He stood up, walking over to the desk.

Tony stood from Clint's dead body. "Hey-"

"We don't have time to argue." Dean started scribbling a list on to a scrap bit of paper. "We need all of this." He handed it to Bruce.

Bruce looked confused. "Wha-"

"It's the ingredients we need for the cure. We'll need to kill Tekin for Clint's, and find out who hit Cas. We need two lots of everything - okay?" He put a hand on Bruce's shoulder.

"O-okay." Bruce grabbed his coat and ran for the door.

"Now, Sammy and Steve, you gotta be here for if they wake up-"

"When they wake up." Tony interjected.

Dean nodded. "They could put up a fight, try and drink from one of you. You gotta keep em in here and stop em drinking - the minute they get any human blood, they can't be cured, you hear?" Dean looked at Steve, the clueless one of the two.

"Yes sir." Steve walked over to Sam and they began to plan.

"What are we doing?" Tony looked at Dean.

"We're going to kick some vampire ass."

Natasha tried to catch her breath. Only two of the original circle of men remained, they both were anxious, having been watching the consistent demise of their former colleagues before them.

"Woah, woah. Hold on." Tekin clapped his hands, then beckoned the two remaining guards over to himself and Mr Buhar. He whispered to them. Natasha took the moment to recompose.
