Ok so this is the longest chapter so far and is probably going to be the last for a while since I've run out of ideas but as soon as I get some more I'll continue it. Thanks to everyone who has reviewed/followed/favorited this story.

I hope you like this chapter :)

They made their way over to where two bikes were parked and all four of them stopped and looked at them. Beckett stood there and looked at Castle's bike, "I'm impressed Castle, it looks almost brand new."

He shrugged, "It was my pride and joy when I brought it and then it was put into storage at the loft so it's been looked after."

Beckett nodded then looked at Tony and Ziva, "How do you want to do this?"

The two agents shrugged, "We honestly don't mind."

Beckett thought for a moment then looked at Ziva, "You've never been on a bike."

Ziva nodded, "Tali was on one when she was killed so I refused my father when he tried to get me to learn."

Beckett nodded and then Tony turned to his partner and asked in a concerned voice, "Are you sure you're going to be ok Zi? We can go without you."

Ziva shook her head and rested her hand on his arm. She looked him in the eye and said, "I'll be fine Tony, as long as you've got my back I'll be fine."

Tony nodded, "Of course Ziva, I've always got your back."

Beckett watched them for a few seconds more before she cleared her throat. The two agents looked at her and she smiled, "How about Ziva rides with me to the impound lot, I've been riding longer than Rick and I'm used to taking passengers."

Ziva and Tony both nodded and Ziva looked incredibly thankful. Beckett smiled and moved to her bike and pulled out her helmet. Castle then watched as she gracefully threw her leg over and got seated, he quickly pulled out his phone and took a picture before turning to his own bike. Over his shoulder Beckett said, "I saw that Castle, you better delete it." She went back to her normal name for him, not carrying about their cover for the minute.

Castle shook his head as he too pulled out his half shell helmet. "Not a chance detective. I think I just found my new caller ID."

Beckett shook her head but didn't say anything, just looked at Ziva and gave the Israeli a reassuring smile, "You'll be fine Ziva, I promise I won't go as fast as I normally do until you get used to the bike."

Ziva nodded then got onto the bike behind Beckett. Tony watched her for a moment, making sure she was comfortable before he got on behind Castle.

Beckett looked over at Castle, "Do you know where we're going Rick?"

Castle shook his head, "Not really, I was just going to follow you."

Beckett nodded and pulled on her helmet, gesturing for the others to do the same. Once everyone had their helmet's on Beckett looked at Ziva once more and smiled again, "You'll be fine, just hold on."

Ziva nodded and put her arms around Beckett's middle as the detective started the bike and slowly made her way out of the garage. Castle watched them go then turned to look at Tony. "You care about her," he stated.

"By the looks of it I feel the same way about her as you do about Detective Beckett," Tony replied.

Both men were silent for a moment then Castle said, "Loving a woman who we can't be with, never a good idea."

Tony shook his head then looked over to where Beckett was slowly driving around the parking lot, getting Ziva used to the bike before they went out on the road. "I don't know how I feel about her. I hate to see her hurting but I can't be with her and I know that so I honestly don't know what to do."

Castle cocked his head to the side, "Why? Why can't you be with her?"

Tony shrugged, "Rule 12." Castle gave him a puzzled look and Tony clarified, "Gibbs has rules and rule 12 is not to date a co-worker."

Castle thought for a moment then said, "Is loving someone really dating? If you love someone the way that I think you love Ziva I don't think Gibbs is going to be able to stop the inevitable."

Tony smiled then looked back at the other bike, "What about you and the detective? What's stopping you?"

Castle sighed, "It's complicated. She says that ever since her mother died she has a wall inside and she can't have the kind of relationship she wants until it's down."

Tony nodded then asked, "How will you know when the wall is down? Why don't you just tell her?"

Castle shook his head, "I did, but she says she doesn't remember." He sighed when he saw the questioning look on the agents face, "When she was shot last summer I told her while she was lying on the ground. I thought it was my last chance and I couldn't let her die without at least telling her how I felt once."

Tony nodded sadly, "How do you mean she says she doesn't remember?"

Castle shrugged, "I think she remembers what I said but I can't be sure, otherwise why else would she have told me about the wall and looked like she was about to kiss me in the bank." He sighed again, "But then I'm keeping something from her too." He looked at Tony, "And I have no clue why I'm telling you this."

Tony shrugged, "Maybe you just need to get it off your chest and since I'll be leaving soon you can trust me not to tell anyone."

Castle nodded, "That could be right." He threw a quick glance over at Beckett and Ziva, who had now stopped and were talking quietly about something, then turned back to Tony, "After she was shot a man called me, told me he was a friend of Montgomery's and that he had made a deal with the people who were trying to kill Kate. If I could keep her away from her mother's case he could keep her safe since he had blackmail material on the people behind the whole thing."

"And you can't tell her what you've done since she can't know or she'll dive back into the case and try to get what you know to lead somewhere."

Castle nodded, "That's exactly it. I want to tell her so much but I'm afraid that is I do she'll wind up dead."

Tony nodded once, "Talk to her Castle. Call her out if you have to and then break it to her. She may hate you for a while but if she loves you, and after that kiss last night I personally think she does, then she'll get over it and the two of you can move on."

Castle nodded his thanks then saw that Beckett and Ziva were on their way back, "Don't tell her about this."

Tony nodded, "It's none of my business."

Castle nodded as Beckett came to a halt beside them. "You ready?" she asked. Both men nodded and Beckett smile, "Then let's go get you a bike."

Ziva and Beckett

The two women rode around the structure slowly at first but they slowly picked up speed as Ziva got more confident although since they were inside they never got above about 10mph.

After a few minutes of driving around Beckett stopped the bike and turned to face Ziva. "Are you ok?"

The ex-assassin nodded, "Yes, thank you for doing this."

Beckett shrugged, "You want to be able to do your part in this op, I can respect that and if I can help you do that I will."

Ziva smiled at then threw a glance over to where Tony and Castle were still sat. She could see that they were both talking about something and from what she could see of Tony's face she guessed it was pretty serious, although she had no idea what. "I wonder what they're talking about," she mussed.

Beckett followed her gaze, "You care about him."

"Who, Tony?" Ziva questioned, shocked by where this conversation was now going.

Beckett nodded, "You can see it in your eyes when you look at him, it was the same way my mom looked at my dad before she died." The last bit was sad in a sad voice.

"And probably similar to the way you look at Castle if that kiss last night was anything to go on," Ziva said, determined to steer the conversation in a different direction. She really didn't want to talk about what she may or may not feel towards Tony DiNozzo, it was too complicated to explain, especially since she wasn't fully sure herself.

Beckett blushed, "It's complicated."

"How? If you love each other how can it be complicated?" Ziva questioned, not understanding the problem.

"Because I've been keeping something from him and I don't know if he'll forgive me for it," Beckett said in quiet voice.

Ziva shook her head, "Whatever it is, I think he loves you enough to forgive you. It may take time but that man loves you almost as much as he loves his daughter." Beckett gave her a shocked look and Ziva laughed quietly, "I read people well detective, it was part of my training at Mossad and he gets the same look in his eye when he looks at you as he does when he looks at his daughter."

Beckett shook her head, clearly not believing her, "He told me he loved me after I was shot and I told him I don't remember."

Ziva looked at her then sighed, "I'm sorry but he is keeping something from you too."

"What?" Beckett exclaimed, searching Ziva's face.

Ziva nodded, "I do not know what but every now and then when he looks he gets this look in his eye that he feels guilty about something and I'm guessing that he's keeping something for you too, something that could seriously harm any kind of future for the two of you which is why he is keeping it to himself."

Beckett looked over at where Castle and Tony were sat talking and saw Castle glance in their direction. She quickly averted her eyes and looked down at the bike.

Ziva noticed this and said, "I think you should talk to him detective, I think that you both need to sort out whatever is keeping you apart."

Beckett nodded, "Thank you Ziva. When this case is over I'll talk to him. If," she continued, "You talk to Tony." Ziva gave her a shocked look and Beckett smiled at her, "I saw how you avoided the question earlier Ziva, I know that you have feelings for Tony but you don't know what to do about it since you're not a hundred per cent sure on what your feelings are." Ziva began to shake her head, to try and deny it but Beckett spoke, "Trust me, talk to him and see what happens."

Ziva nodded, "Maybe I will, what's the worst that could happen?"

Beckett nodded and then the two of them spent the next few seconds on silence. "Are you ready to go Ziva?" Beckett asked.

She nodded, "I am thank you."

Beckett smiled and slowly drove back over to where they had left Tony and Castle.

Castle nodded as she came to a halt beside them, before asking, "You ready?" When both men nodded Beckett smile, "Then let's go get you a bike."
