Hey, couldn't resist writing a crossover. I have recently fallen in love with The Walking Dead and needed to write this. This is set in early season 4 of Castle and season 3 of TWD.

I don't own either of the two shows. If I did Shane would have died a long time ago.

I decided that I would make Kate go through the same thing that Rick did, since the similar situations, but paths will be crossed.

It's kind of OOC I guess.

On with the show!

Walkers and Casketts

When Kate Beckett's eyes popped open she noticed two things: her chest hurt like hell and it was too quiet. She looked around the room she was in noticing the machine that was still beeping rapidly along with her heartbeat. She called out for help but no one came. "Castle! Castle! RICK!" she called but nobody came. She thought that there must be something horribly wrong if Castle wasn't there. She had had hallucinations that he was there or little glimpses of what was happening. After sitting there contemplating about what could be going on she decided to get out of bed.

She walked out of her room very cautiously not knowing what she was going to run into and not wanting to rip her stitches. She noticed that the place looked abandoned. As she squinted her eyes to get used to the lighting she noticed a corpse at the end of the hall and ran the other way in terror. She ran through a door that led outside, but what she found made her stomach flip. She wanted to toss whatever she had last eaten but that wasn't much, for she had been in a coma for four months. There in front of her were bodies. Piles of them. She walked by noticing that they had all been shot in the head between the eyes. She noticed her ex-boyfriend Josh in one of the heaps and remembered glimpses of a break up speech that she wasn't sure ever got put to use. Too late now she thought. She ran out of the parking lot to find somebody, anybody, that wasn't dead. As she ran she thought of Castle and the gang back at the 12th and decided to go there since it was only a few blocks away. She really hoped that they weren't dead, especially Castle.

As she was walking down the street she noticed a person coming towards her at a slow pace. It's probably barely noon and you're already drunk? How pathetic. She thought about the man, but decided to ask him if he knew what was going on, but before she could reach him a shot was fired and he fell to ground. She turned around to see who had shot him she was shocked to Castle standing there pointing a gun at her. She looked awful. His eyes were filled with fear and despair. He looked like he could really use a good long hug and a shower. She started to walk towards him but he only straitened his posture and was ready to fire. "Castle, what are doing? Why did you shoot him?" she asked him.

"Kate, you're alive! You're alive! Thank God, I wouldn't have been able to shoot you," he told her running towards her and rapped her up in a big hug. "I thought you were one of them," he said into her hair while holding her tight.

"Castle, what's going on? Why did you shoot that man?" she asked him very confused.

"He's dead Kate," he said as if it were the most obvious thing in the world.

"Yeah, I get that you killed him. Why?"

"No, he was already dead. Come look," he told her grabbing her hand and walking towards the body. When they approached him, Kate noticed that his clothes were tattered and his face look like seven-day-old decayed flesh.

"What's wrong with him?"

"He's a zombie," he told her seriously knowing that she wouldn't believe him at first.

"Whatever! Are we in one of your dreams? Wake me up!" she started to freak out

"Kate, this isn't a dream. It's real. It happened about three weeks after you were shot. It's some kind of virus I think. I'm not entirely sure. What I do know is that the world has completely changed since you went into your coma and we're lucky to be alive," he told her sincerely.

"Who's left?" she asked all of a sudden afraid of what she might here.

"Well, there's me, my mother, Alexis, Ryan, Espo, and Lanie. Oh and your dad. And you. We're extremely lucky to still have everybody. Well except Jenny. Ryan's taking it really hard. I mean I completely understand. The only reason I'm still sane is the small amount of hope that I had that you were still alive somewhere. I couldn't go back to hospital, because it was too dangerous. That place was filled with them. I'm surprised you got out," he told her.

"Yeah, I saw the bodies. All of them," she said remembering Josh's face and shuddering at the picture of the hole between his eyes and the other one that accompanied it in the back of his head that was about the size of her palm.

"Well I'm glad you managed to get here," he told her as he took her and started to walk towards the precinct.

"Castle, wait," she said as she pulled him back by his hand and brought her mouth to his in a heated and passion filled kiss. The two finally pulled back after a couple minutes in need of oxygen. "I love you too," she told him while looking into eyes and leaned in for another kiss, except this one was cut short by a moan.

Cliffhanger! Reviews are much appreciated. Thanks for reading.
