A/N: Just a one-shot that I had fun writing. Set any time after Season 4. Hope you enjoy. CN :)

''Chuck, move it, now!'' Casey yelled as he pushed Chuck forward through the commotion.

''I can't go any faster! Where's Morgan!'' he yelled back over the shouts of the others.

''I'll go back and look for him! You go back to base and defend!'' Casey yelled back.

''I'm not leaving you! Or Morgan!'' Chuck yelled back as they ducked to avoid being seen.

''Do it Chuck!'' Casey told him before running back the way they had come.

Chuck was torn between going back to find Morgan or going to defend the base. After a moment of deliberation, he placed Morgan's fate with Casey and ran ahead.

Meanwhile, Casey whipped around the corner, gun at the ready. He glanced around, making sure he wasn't being followed. He heard shouts, but in the distance. He silently walked along the corridor before whipping round the next corner. That's when he saw the red. It was too late… Morgan was gone. He swore out loud before running to help Chuck; it was just them now.

Chuck was nearly at the base when Sarah appeared, her gun pointed straight at him.

''Sarah, please; don't do this!'' he yelled at her pleadingly.

''Why wouldn't I? It was you that killed Carina… I saw it, Chuck''

''She would've done the same to one of us, Sarah'' he tried to tell her, but she shook her head before smirking.

''This is for her'' she pulled the trigger and watched the red appear, smirking.

She saw movement from the corner of her eye, but it was too late. Her gun was down by her side, she was vulnerable, and Casey was there, ready to pull the trigger.

Casey glanced down at Chuck before looking back at Sarah.

''He didn't even have his weapon'' he growled out.

''Shame'' she smirked, trying to buy time.

''You killed Morgan in cold blood''

''Yeah, which means you're teams gone Casey. You don't have anyone to watch your back'' she smiled, and Casey suddenly felt like he was in a trap. He heard the movement behind him, and then he saw the appear. His own daughter had betrayed him. He sunk to his knees.

Sarah watched him for a moment as the room fell silent.

She kept her straight face before she chucked her gun on the floor, crossed her arms, and laughed.

''Casey… Morgan, Chuck and even Carina died more realistically than that'' she raised her eyebrows.

''Hey, you're lucky I'm even playing this game, never mind playing dead'' he retorted as he took the sensor and now bright red wristband off. Chuck sat up and took his off too, grinning. He took the microphone from inside the makeshift base his team had made out of Castle's tables and chairs and talked into it, his voice ringing throughout Castle.

''Games over guys; girls won, we're in the main room''

Alex high fived Sarah and looked apologetically at her dad as Morgan and Carina appeared around the corner, the latter smirking.

''So I didn't sacrifice myself for nothing then?'' she asked.

''Uh, I shot you, you didn't sacrifice yourself'' Chuck pointed out

''When her back was turned'' Sarah smiled as she took off her green wristband, signalling she was still 'alive'.

''I like to think that I was so quiet, she couldn't hear me, therefore technically-'' Sarah silenced him with a kiss, smirking.

''Sorry I died guys, I panicked when I couldn't find you'' Morgan sat down beside Alex in the newly furbished Castle.

Casey growled while Chuck clapped him on the back. There was a small silence before Casey cleared his throat and spoke up.

''Anyone up for a rematch?'' he asked, growling at the laughter he got.

It had taken two hours to persuade him to play.

I was watching an early episode of ABC's 'Castle', and Alexis and Castle had a play gun fight. I guess you could say it inspired me and this idea sprung to mind. No idea if the whole wristband/sensor thing is real, but hey, it's fiction! Thanks for reading. CN :)
