Thursday

Oh you're in my veins

And I cannot get you out

Oh you're all I taste

At night inside of my mouth

Andrew Belle-In my veins

Kate was inside her car Thursday night, waiting for the suspect who she was investigating appear, one of Bracken's men that was still free, the one the angel had told her about, receiving orders from him from the jail. Beside her, angel Castle continued to follow her and although things had ended badly on the night before, he continued to insist on appearing, even knowing that Kate would be angry, but it would be a start because sometimes she would talk to him without realizing it.

That morning had been difficult because he had seen Kate going out with Eric for lunch.

"Ready Kate?" The man asked, kissing her cheek and helping her put on her coat and Kate gave Eric a small smile in agreement, and the angel asked, sad:

"Are you really going out with him?"

"Sure, it's all for Castle..." She said, with passion. "And it's only a business lunch, to talk about the search and..." Kate stopped talking, realizing that Eric was staring at her.

"Kate, are you ok?" The millionaire asked worried and she nodded, tired. "Shall we go?"

Jealous, Castle crossed his arms and disappeared. Kate said yes to Eric, though discouraged by the angel who suddenly disappeared, but then she shook her head.

"Let's go, Eric." He led her to the elevator, while Castle watched, invisible to her, devastated as Eric was doing with Kate everything he wanted to do.

Despite the jealous, he knew Kate would never get involved with him, because he knew she love him and he then discovered she'd had lunch with him so Eric could tell her about his contacts that were helping in Castle's searches and was grateful for that.

"How long it will take him to get out?" Kate asked to the annoying angel.

"I entered his apartment, he's armed and getting ready." The angel was excited because it would be his first police chase.

"You're like Castle, following me around." She said, shaking her head and staring at the window.

"Kate, I am Castle, only in the form of an angel." He said again, desperate, touching her shoulder and Kate bit her lip, getting away from him abruptly, making him sad. "Why it's so hard for you to believe?"

"Because if you're an angel, it means that you died, and I can't lose Castle." She said aloud when then Esposito appeared at the window and asked worriedly:

"Beckett, are you okay?"

"Yes." She said flushing and he nodded, before going to his post.

The building door opened and Kate became a detective again. "Real or not, I don't want you to follow me out there, okay?"

And Kate got out, showing the badge to the suspect.

"NYPD, freeze!"

The man turned around and quickly took the gun, pointing it at her.

"Put the gun down!"

He started firing but Kate hit him on the shoulder and in the hand, disarming him when then angel Castle shouted:

"Kate, watch out!"

A car with a man using a gun was driving at high speed and was about to hit the detective, while two men in the back seat started firing with their guns but Castle caught her in his arms, lifting her, making a breath of air move the car toward a post, while his wings protected her from the bullets.

Kate was still lying on the ground with Castle body over her and his wings hiding them. Castle's forehead was touching hers, while his hands interlaced with hers beside her head, his face deadly serious when it came to his fiancée's safety.

"You never listen to me... Being man or angel." She whispered with a smile that she only gave to Castle.

"I'm your guardian angel. Now do you believe me?" He asked, unsure.

There was no doubt. He had been her guardian, taking care of her, bringing coffee, putting socks on her feet, saving her from the rain of bullets.

"I do. Oh Rick, I've missed you... My angel."

Both had tears in their eyes and Kate wiped his eye, before leaning up and kissing him. Their lips were lightly pressed on each other's, before Kate put more pressure on the kiss, both lost in the moment.

But the kiss was interrupted when Esposito and Ryan appeared, seeing their boss still on the floor, flushed. Castle flew up and saw Isaac, who smiled in approval for the mission.
