Kate Beckett sat at her desk hoping 5 o'clock would come soon the constant irritation of Castle could only be taken for so long before someone got hurt, namely him.

"Beckett, why were you so against killer shape shifters?" Castle suddenly piped up.

"Do you really need an answer to that other then they don't exist ." Beckett was now slightly annoyed.

Castle opened his mouth to talk but captain 'Iron' Gates interrupted. "Ok detectives you can go." She said with a sigh. Beckett nearly set off running to the elevator once Gates was back in her office.

"What's the hurry Beckett I'm sure the murderous villains can give you a break tonight?" Castle chirped.

"I just need to get home castle the full moon brings out all kinds of crazy." Beckett pressed the button to call the elevator.

After saying a quick goodbye Castle and Beckett went their respected ways for the night.

Once at home Beckett settled down with a tub of ice cream and a movie. Just then there was a knock at the door. 'I'm going to kill Castle' Beckett thought. She walked over to the door and opened it.

"Castle what are you doing here?" Beckett asked.

"Nice to see you too detective." Castle said sarcastically.

"Castle you need to go." Beckett nervously pleaded.

"I need to talk to you." Castle insisted.

Beckett let castle Step inside, before hurrying into the kitchen and made them coffee.

"What about?" Becket questioned from the kitchen.

"Why don't you believe shape shifters?" Castle smirked.

"They don't exist Castle so drop it." Becket agitatedly replied.

Just then black veines started to appear on Becket's hands and neck. She hid it well and Castle didn't notice. Becket stood up and walked to the bedroom. "I'll be right back." She told castle.

Once Becket was in her bedroom, she calmed down. This hasn't happened since she was 14. The veines never showed anymore and the transformations never happened. Suddenly Castle knocked on her bedroom door.

"Beckett are you ok in there. I keep hearing growling." Castle said through the door.

"I'm fine honest" She replied opening the door. "You should go Castle I'm really tired I'm sorry."

"Ok until tomorrow Kate." With that he left.
