Watched Tick Tick Tick this evening, and just had to imagine what was going on in their minds during this episode. I don't own anything about Castle, outside of my own imagination.

Italics are the thoughts in their heads.

Oblivious to the drama that was unfolding, Kate continues her shower. After a long few days, and tension around the case,, she decided for some personal time. She thought she heard her cell phone, but just stayed in the bathroom. Whoever it is can wait. I need a few minutes of "me time".

The phone continues to ring, intruding on her musings. With a sigh, she shuts off the water, and slowly gets out of the shower.

Castle throws money at the cab drive, dashing out of the car. "Come on Beckett, pick it up" he mutters, getting more nervous as the rings continue. "Pick up the phone! Pick it up!" I'll never get there. Come on feet, move!

She grimaces at the phone. It's Castle. "What Castle?" she sighs, waiting to hear his newest theory or story line.

Breath coming fast, he continues to run, pushing past people on the street. Gotta love New Yorkers, just a bunch of dirty looks as I push forward. "It wasn't Ben Conrad! He's not the killer!" he shouted, desperation in his voice. "The killer's still alive."

Kate opens her mouth in shock, wondering how they could have missed something. They had been scrambling around on this case, and she thought the interaction with FBI threw her off her game. She hears beeping, and starts to turn, hearing the chilling voice from the apartment. "Goodbye Nikki. Goodbye Nikki"

Castle screamed "Kate!" as he turned the corner. His heart stopped as he heard the explosion and saw the blast of flame. Oh no! Not Kate! He took a deep breath, and rushed across the street. Even jaded New Yorkers stood in street, jaws to the ground. He pushed through the crowd, as he dialed Javi. "Esposito! It's Castle. Beckett's place – "

"Oh geez, you there again Castle? What protection are you providing now –"

"Esposito, it's Kate. Her place, he's not dead, I don't know if she was there" he rambled as he ran the stairs to her floor. "Get over here. I'm going to find her." He hung up before Esposito could respond, hearing sirens in the background.
