A/N: Welcome to Chapter 3.

I'm in a weird mood , but I felt like I should update because...Idk I don't have a good reason.

Sorry for any mistakes or anything.

And then, he just didn't think.

The day that Zach was due to return home from his mission, Preston decided that it would probably be best if he went to stay at a hotel for a while.

"It's alright, honestly. I don't mind."
"You don't have to leave, you know." Cammie repeated herself for the third time today.

"I do. I'll be invading your space if I stay any longer."

"No, you won't."
"You and Zach need your space, and I think I need mine. It's alright Cam."

"If you're sure. But you know you're always welcome, right?"

"I know." He smiled, picked up his suitcase and walked to the door. "Thank you." He said as he walked out to his car, put his suitcase in and drove away.

That night, in his hotel room, Preston couldn't sleep.

He knew that Zach was home now. Zach had called him when he got home. He told Preston that he was okay, and that the mission went well. And that now he was home, with Cammie.

As much as he tried to block it out, the only thing he could think about was what had happened between him and Cammie. At first, it had seemed like nothing but a little, not-so-innocent now? Now he couldn't shake Cammie from his mind.

But he felt guilty. He thought of how Zach was back in his house with Cammie. How they were probably laughing and talking and kissing. And Zach knew nothing. Zach had no idea at all.

He ignored it as best as he could. He had agreed with Cammie that he wouldn't say anything. He had promised her, they had promised each other. So he couldn't say anything. He wouldn't say anything.

Not yet, anyway.

It took him two days.

Two days of small talk over the phone with Zach.

Two days of lying to his best friend.

Two days of keeping secrets from him.

Two days.

So he arranged to meet him in the bar that Zach, Cammie, Macey and Preston would usually go to together. Because he had to tell him. Zach had to know.

It wasn't fair, it wasn't right.

Preston knew that by telling Zach, he was essentially throwing away any decent friendships he currently had. He'd lose Zach, he'd lose Cammie and he'd already lost Macey.

But before he could change his mind, Zach walked into the bar where Preston was already sitting and sat right opposite him.

"Hey!" Zach greeted happily.

"Hey." Preston smiled back. Although he was freakishly worked up and very nervous about how Zach was going to react, he was happy to see his best friend.

"How've you been?" Zach said after ordering his drink.

"Me? I've been fine...great actually.." Preston's mind was in a different place, and didn't really want to correspond with his voice.

"Cam told me." Zach stated plainly and Preston's eye's nearly popped out of his head.

How do I respond to this? He thought. But he just replied with "Told you what?" and kept quiet.

"She told me about the whole thing with Macey."

Preston mentally breathed a sigh of relief and thanked whatever deity was above him for Cammie's loyalty and ability to keep secrets. Secrets, which he was about to share.

"Oh, right. Yeah..."

"And by your tone of voice and facial expression, we are absolutely not talking about it."
"That sounds like a very good idea."

"But seriously. I'm running round trying not to get myself killed in Estonia, and you're breaking up with your girlfriend. I thought you were gonna propose or something, not take off at 4 in the morning."
"Zach..."

"I know, I said I wasn't gonna talk about it. I'll shut up."

"Good."

"Cam said you were staying at the house while I was gone, you didn't have to leave you know."

"I know, but..."
"But?"

"I don't know... It would've been awkward."
"Why would it have been awkward?"

"I figured you two would've wanted some time alone... because...you know."

"Ah that's fair enough. And I suppose that would've been quite awkward. Cam can be a bit...loud."
"Yeah, I know." he laughed, before realising what he'd said.

It slipped out before Preston could take it back. Did he actually just tell Zach? Indirectly.

"Wait, what?" Zach had picked up on it. Obviously.

"Nothing...I didn't mean...It's just what you say...right?"

"No, Preston. It isn't."

"Well...oops?" the exclamation was less of an exclamation, and more of a question.

"Oops, you didn't mean to say it? Or oops, you need to tell me something?"

"Well I didn't mean to say it..."

"Okay, Preston. I'm your best friend, and in my profession we're trained to detect lies. However, with you I don't have to use any kind of technique because you're a crap liar. If something's going on, you need to tell me. Like, now."

"Nothing's going on as such."

"But?"

"But something may have happened?" It came out like a question again.

"Something may have happened? Something may have...? Preston, stop bullshitting and just tell me what's gone on. I may be a spy, but I'm not psychic."

"Me and Cammie...I... We..."

"Preston. Get to the goddamn point."

"Do I need to say it? You know what I'm going to say."

"Like I said, I'm not a psychic. So funnily enough, I don't know." Zach retorted, but it was clear that he had his assumptions.
"We slept together! Okay. Is that it? Is that what you wanted me to say? But I'm sorry and I've wanted to tell you since you got back because I've felt so guilty and.."
"Shut the hell up."
"But."
"Shut. Up."
So Preston fell silent, and waited for Zach to start asking questions as he knew he would.

A minute was all it took. "When did it happen?" Zach asked.

"The first time was..."

"Wait, first time? You mean to tell me it happened more than once?"

"Twice. It happened twice."

"Yeah, that falls under the category of more-than-once, Preston."

"The first time was the night after I left Macey.."

"And the second?"

"The night before you got back..."
And before Preston could even say anything else, Zach extended his right arm and punched him straight in the jaw.

"Shit that hurt." Zach exclaimed, staring at his fist which was now bleeding.

"No kidding."

Preston would've retaliated, but he had half expected the punch. So he just stood there with his hand on his jaw where he'd been hit.

"You feel better for that?" Preston asked, trying to get a reaction out of Zach. He knew that he was the one in the wrong, but he wasn't going to stand there and let his best friend punch him.

"Well, I might as well hit again. Seeing as doing things twice seems to be the trend right now."

"Look, I apologised..."

"You think an 'I'm sorry' excludes the fact that you slept with my girlfriend, twice?"

"You weren't properly together at the time! I highly doubt that you were completely alone during your time in Estonia. How many girls did you have on the go at once Zach? Two, three? We all know what you're like. Even Cammie knows."
"Do you want me to punch you again, Winters? Because it really sounds like it right now."

"Look, Zach. I came here because I wanted to tell you. No, I needed to tell you. Because for the last few nights I've been lying awake, ridden with guilt because I've been keeping this from you. I get that you're pissed off at me, okay? I get it, and I expected it. So I'm gonna go, because you need space."
"Damn right I do." Zach snapped.

"Bye Zach." Preston said, getting up, walking away and wishing none of that had happened.

It was 10:30pm when Zach burst through the front door of his and Cammie's house. She came into the hall immediately after hearing him enter the house so loudly.

"Hey." She said, oblivious of what was to come.

"Seriously? Hey?" His voice was cold, and she could hear the anger.

"You seem tense...and a little angry. What's wrong?"

"What's...? What's wrong? What do you think is wrong?"

"I don't know Zach, that's why I'm asking you. You were fine before you went to meet Preston and now...Oh god."

"Got it yet, Gallagher Girl?"

Cammie just stood there in silence. Complete and total silence. After all, what could she say? He knew now. And everything was different.

"Zach...I..I..."

"Save it, Cam."

"We were taking a break." She managed to get out, but it came out as more of a sigh than an actual sentence.

"I know that. But I didn't realise that we were taking a break so that you could screw Preston."
"I didn't mean for it to happen, Zach."
"Why does that not surprise me?" He pushed past her, walked upstairs and began to pack a bag.

"Zach...Zach, what are you doing?" Cammie was close to tears, which was unlike her.

"What does it look like, Cammie?"

"You don't have to leave. We can talk about this."

"There isn't anything to talk about. I need space. We need space."

"I know. I know that but you don't have to go tonight..."

"Yes, Cam, I do." He replied bluntly, grabbing the bag he'd packed and walking back downstairs with Cammie following close behind him. He put his hand on the front door, ready to open it just as Cammie spoke

"Zach..."

"What?" He turned to face her.

"I'm sorry."

And without even a one-word reply, he turned back around and left the house. The second he closed the door, Cammie sat down on the bottom step of the staircase and sighed. With her head in her hands and tears on her cheeks, she racked her brain for ideas about what to do.

She couldn't call Macey. And even if she did, there was no guarantee that she'd even answer. She didn't want to call Liz, because she'd have to explain everything to her and she figured that Liz would probably judge her for what she'd done.

So she grabbed her phone from her pocket, and hit the first speed dial contact she saw. Within 2 rings, the call was answered.

"Hey Cam, you alright?"

"Bex, I've gotta talk to you. I've really messed up..."

A/N: And there goes that.
