Chapter 1

She follows the ambulance to the hospital. She can only pray he doesn't die. With him would go her only lead on solving her case.

At the hospital, she flashes her badge at the admissions nurse.

"I'm Detective Kate Beckett, Homicide," she says tersely. "You have a patient, multiple gunshots. Just brought in. I need his status."

"Detective Beckett, you're going to have to wait. The doctor is with him now," the nurse explains.

That isn't what Beckett wants to hear. If this guy dies, then it's on her. She wasn't paying attention. And next thing she knew, bullets were flying. All she could do was fire back to save herself and her team. She's grateful Castle wasn't there. Her being distracted could have gotten the man she loved killed if he had been there.

"He goes nowhere without me knowing, do you understand?" Beckett snaps. "He is my main suspect and I'm not losing him."

Beckett stomps down the hall to stand and wait where she will be able to see all the action. Several minutes later, the door to her suspect's room opens. She finishes the text she's sending to Castle, letting him know where she is, before looking up.

"Detective Beckett," the approaching doctor smiles charmingly at her.

"Josh," she gasps in shock. "What are you doing here?"

"Apparently, saving your suspect's life," he grins. "How are you?"

"Fine," she answers, still a bit off balance. "How's my suspect?"

"They're taking him to surgery now. It's probably going to be a couple of hours before they're done."

"You doing the surgery?" she asks.

"Not this one. My rotation is in the ER. I handle the emergencies and traumas as they come in."

She just nods, not really knowing what to say to him. It's not like they ended on bad terms. But they ended all the same. And they ended because it was what she wanted, not him. Things are awkward now because of it.

"Okay, then. I'm sure you're pretty busy," she hints. "I won't keep you."

"A beautiful woman is never a bother," he laughs, lifting a hand to stroke her cheek. "I've missed you, Kate."

"Josh, don't," she warns, stepping away from him. "A lot has changed. I'm sure we're both different people now."

"Dr. Davidson, we need you in Trauma 1," a voice calls out to him. He scowls in frustration.

"We should catch up," he calls to her as he runs toward his latest emergency. "We have unfinished business."

Unfinished for him, maybe. Beckett just shakes her head. She has a bad feeling things are about to get complicated.

"Beckett!"

She looks up from where she's sitting to see Castle flying down the hall towards her. Before she can say anything, he has her swooped up in his arms and is holding her so tight she can hardly breathe.

"Thank God," he whispers over and over into her ear. "Thank God you're okay."

"What do you mean?" She manages to wiggle from his grasp, then leads him to the seat next to her own. "Sit down before you fall down. You're shaking."

"I was so scared," he says, unable to stop touching her. He runs his hands over her arms, making sure she's unhurt. "I heard about the gunfire, then I heard you were here … I didn't know what to think."

"Oh, Castle," she sighs, pulling him into her arms. "I'm so sorry. I texted to tell you I was here at the hospital because I didn't want you to worry where I was. I didn't think you'd be afraid I was hurt."

"You're fine," he says, more to convince himself of that fact. "That's all that matters. I love you."

He kisses her. She allows it for longer than she'd normally allow in public. He needs the reassurance and frankly, so does she. Seeing Josh shook her more than she wants to realize.

"Now that you're here, you can keep me company," she smiles. "The perp is in surgery. Hopefully I'll be able to question him once he gets out."

The longer he sits with her, the more he starts to relax, realizing she really is okay. When he's back to his normal, wise cracking self, she decides to drop the bomb on him.

"You'll never guess who his doctor is," she grins, trying to make light of the situation.

"Doctor Who? Doctor Spock? Ooh, Doctor Frankenstein," he says, his excitement growing with each ridiculous guess. She decides to stop him before he goes off on some tangent she won't be able to wrangle him down from.

"Okay, stop guessing!" she laughs. "Josh is his doctor."

That revelation kills his smile.

"Josh Josh. Like as in Dr. Motorcycle Boy?" he scowls.

"One in the same," she nods. "He's apparently back from Haiti or wherever Lanie said he was."

"Did you know he was back?"

She tries not to take offense at his question. She can understand his insecurity about the man so she gives him a break this once.

"No. Once we broke up, that was it," she assures him. "I haven't spoken to him since not long after my shooting. I had no idea he was even in the country, let alone in the city and at this hospital. I don't really care. I just didn't want you blindsided when or if you saw him."

"And?"

"And what?" she asks. "Nothing at all happened. He told me my suspect was in surgery, then got called away on an emergency. End of story."

"Did you tell him about us?" Castle wonders.

"I will, okay?" She places a hand on his cheek. "I promise. I'm not trying to lead him on or let him think he has any kind of a chance with me. Please trust me."

He takes her hand in his own and places kiss on her palm.

"I do. Trust you, that is," he qualifies. "Him, I'm not so sure about. If it were me, I'd never get over you. If you were the one who got away from me, I wouldn't give up until I got you back."

"He's not a bad guy, Castle. He just wasn't the guy for me," she shrugs.

Her nonchalance reassures him. He can see she has no residual feelings for Josh. He just wishes he felt the same way.

From the very beginning, Josh Davidson bothered him on a level he could never really name. At first, it was shock at the man's existence. The fact that Beckett never told him about Josh bugged him. Even though Castle was dating Gina at the time, it hurt that she'd keep something like that from him. Eventually, the jealousy gave way to anger and resentment. Especially after Castle ended things with Gina. Despite the fact that Beckett was in a serious relationship with Josh, that was the time Castle and Beckett began to grow closer and closer. But any time Castle thought he was finally about to have an important moment with Beckett, Josh would turn up. The man seemed to show up or call right when Beckett and Castle were on the verge of crossing that line. It happened when they were locked in that freezer. It happened after that case they solved for that soap opera. For that alone, he found plenty reason to hate the man.

But what really puts a blinding rage in his eyes whenever the man's name is even mentioned is what happened after Beckett's shooting. She was still in surgery when Josh's assault came. The verbal jab hurt worse than the physical shove. Josh blaming Castle for Beckett's shooting was too close to what Castle was telling himself. Then to see her laughing with him and touching him while in her hospital bed. Then sending him away and never calling. He spent those whole two months seething with jealousy and rage that Josh got to be there with her while she wanted nothing to do with Castle. It nearly killed him every day he didn't see her to imagine she was spending that time with Josh.

The day she told him Josh was out of her life was one of the best. He finally believed they had a chance. She spoke of needing to tear down walls and he was content to let her take all the time she needed to do so. In the end, it paid off. He got the girl. Now, Josh just has to realize that and accept defeat. Castle hopes it will be just that easy, but something inside is reminding him that with issues involving Beckett, things are never that simple.
