When he finally came home, Greg didn't know what to do. He wanted to call Brass and report what just happened, but he wasn't sure it was the right thing to do. Why didn't Julian want that?

He would've loved to call Nick and tell him about tonight, but he knew how he'd react. He wasn't sure if he was the right person to talk to. But who could he talk to, then? There was no one. No one who wouldn't tell him to talk to Brass about this. And maybe this was the right thing to do. Or maybe not. He was confused. What happened with Julian? Where did all this aggression come from?

"Give me a good reason not to tell Brass about this," Greg said, talking with Julian on the phone.

"...Please just don't do it, alright?" Julian sounded calm now. He sounded like he usually did.

"...Did you take any drugs? Is that what you're afraid of?"

"What makes you think that? No!"

"Then why didn't we report this? I feel really bad about it! We let these criminals get away!"

"We don't know their names or anything else, anyways. We have nothing to help find them. I defended us. That's all that happened."

Greg sighed. "Why did you even stop and talk to them? You provoked them!"

"Excuse me? They started it!"

"No, they wouldn't have bothered us if we just kept walking. You picked up a fight. It was stupid and dangerous to do that!"

"You want me to apologize for saving you?"

"Saving me?" Greg knew it was a bad idea to call him. "I'm gonna hang up now."

"Are you mad at me? What for?"

He sighed again. "Take a wild guess." He hung up.

When Julian heard Greg hanging up, he went crazy. He threw his phone against the wall, knocked over several pieces of furniture and even smashed a mirror.

The next shift started off weird. Julian kept looking at Greg in the locker room, in the hallway and in the break room, but didn't say anything. Greg noticed the looks, but tried not to care. He didn't want to talk to him. He was angry with him and didn't understand what happened last night. He got them in a dangerous situation for no reason, and didn't want to report the incident to Brass, for no obvious reason. And to top it all off, he was aggressive towards Greg when he wanted to call Brass. He even had a bruise on his wrist, caused by Julian. He hid it with long sleeves because he knew there would be questions asked if someone saw it. He still felt very bad about not reporting the incident. If these three men would hurt someone else, he'd feel responsible for it. He needed to find those guys, but Julian was right. They didn't know their names or anything to ID them. They saw their faces, but that's about it. No hard evidence like DNA available, so how could they find them. Greg had an idea, but he had to go to a crime scene, first.

A 46-year old man was found dead in his house. His wife and children were found dead, too. Greg, Sara and Nick were assigned to the case. When they arrived at the scene, Brass was already waiting for them.

"Come on, they're over there," he said while leading them into the house.

David was already with the bodies. The husband was sitting on the couch, the children were lying in the kitchen and the mother was in the bathtub.

Sara walked around the premises to look for evidence. In the meantime, Nick and Greg were assisting David with the bodies.

"No, no, no!" Nick said hastily. "That's not working." Him and David were trying to get the woman out of the bathtub. The tub was filled with water, but she still had her clothes on. The wet clothes made her much heavier than she already was, making it hard for Nick and David to get her out of there. "Greg, could you give us a hand?"

Greg was just about to follow a blood trail leaving outside the bathroom. He turned around to look at Nick. Helping them get the body out of there would require rolling up the sleeves of his shirt. Well, there was no way out of this situation that wouldn't make him look like a jerk, so he had to do it. So he rolled his sleeves up and assisted Nick and David with getting the body out.

"What happened to your wrist?", Brass asked as he walked in, watching them get the body out.

"I caught it in a door," he replied, trying to hide the shame in his voice.

Brass, David and Nick shared a look Greg noticed. How foolish of him to think they'd buy this lie. After all, they see bruises all the time and are able to distinguish different kinds of bruises, and this one obviously wasn't from catching one's hand in a door.

"It looks bad. Did you go see a doctor?" Nick asked, knowing something was fishy about the explanation.

He shook his head. "Doesn't even hurt anymore."

When they arrived back at the lab, Nick leaded Greg into their office quite ruggedly. "Will you tell me what's going on with you?" he asked roughly.

"What?" he asked, playing dumb.

"How about you start with what really happened to your wrist?"

"I already told you, Nick," he replied impatient.

"Right. You caught the hand in a door."

"Yeah. I'm sorry if you expected something else," he replied, acting as if Nick was paranoid for thinking he lied.

"Show me that bruise."

"Excuse me?"

"Show it to me."

"Why?"

"Because. I want to take a look at it. See if something's broken."

"You're not a doctor and it's fine. I told you, it doesn't even hurt."

Nick grabbed Greg's wrist, causing him to contort his face and groan with pain. "So that's what it looks like when something doesn't hurt, huh?"

"It doesn't hurt unless a jerk twists it!" Greg replied sarcastically, walking over to the door.

"Wait." He grabbed Greg's arm, keeping him from walking out the room, but also looking at the wrist. "I've seen this kind of bruise before... Who did this to you?" he asked both angry and concerned, but before Greg could answer, he said, "Julian... I'll KILL him!"

"No! It wasn't him!" Greg replied, desperately trying to keep Nick from storming out.

"Why the hell do you keep defending this son of a bitch?"

"I'm not! But he didn't do this!"

"Oh yeah? Then who did?"

"I told you, I caught my hand in a door..." Greg thought it would be best to stick to this story, despite knowing he wouldn't believe himself, either.

"Get out of my way, I'll kick his ass!" Nick shoved Greg to the side and stormed into the DNA lab.

"Julian!" Nick yelled as he walked in, followed by Greg.

The lab was empty. Greg sighed in relief.

"Where the hell is he?"

"Would you PLEASE calm down already? I told you what happened, this has nothing to do with Julian!"

"Yeah right..." he said, slowly calming down a bit. "Oh I remember, he's always out somewhere on his lunch break... Hand me your cell phone."

"Nick, are you out of your mind? Leave him alone."

"I don't have his number, now come on!"

"I can't, it's broken."

Nick rolled his eyes. "Why the hell do you keep doing this? What did he do to you? Are you afraid of him?"

"God dammit, Nick!" Greg said angrily. He knew Nick only worried about him, but he sometimes acted like Greg was a little boy that needed to be protected from everything. He was totally right to worry right now, but Greg didn't really want to admit that. "Come on!" He walked him back into the office.

"Alright... I'll tell you what happened, but you have to promise me you won't talk to ANYONE about this, alright? Not, Brass, not Sara, not Julian."

Nick raised an eyebrow. "I don't know I can promise that."

"You have to! This won't leave this room, you got it?"

"...Go ahead," he leaned against the table and folded his arms.

Greg went on the tell him everything, starting from the nice conversations they had at dinner to the phone call they had after Greg got home, and everything in between.

Nick didn't know what to say. That's certainly not what he expected.

Greg sat down on a chair, waiting for Nick's reaction. Nick didn't look nearly as mad as Greg expected him to look like. "Say something." He couldn't take the silence anymore.

Nick walked around the room a few times. Then he sat down as well. "Are you alright?" he asked very compassionate.

Greg was surprised. He didn't expect to see Nick's soft side now. He shrugged his shoulder. "It's okay... I just... I just don't know what to do."

"For starters, talk to Catherine about it. She needs to know about his aggressions."

Greg shook his head. "No, I can't do that."

"Greg, you..."

"No! It could get him fired!"

"So...? I know you thought he was your friend, but that's obviously not the case. He's lazy and never does his job as quick as he could. You know that, he's a bad DNA tech."

"I can't ruin his life like that. Besides, maybe there's a reason for all of this..."

"Like what?" Nick asked rather annoyed.

"I don't know... Maybe I should talk to him..."

"What? No! Stay away from him! He's dangerous."

"Come on, I don't think he is... And what could he do to me at the lab?"

Nick wasn't able to talk Greg out of this, but he was just glad nothing worse happened that night. He still thought Julian was dangerous and should be fired, but he promised Greg not to tell anyone, and he didn't.

"And what about these guys? You'll let them get off with this?"

"The only way to find them is if they show up at a hospital... I thought I'd call all the hospitals in Vegas and ask if they have any new patients that fit the description."

"And if they do?"

"Then I'll go to Brass with this information. If not, there's no point in telling him."

Nick nodded. Of course he'd prefer if Greg just told Brass about this, but he could also understand that he didn't want to do that. He didn't care for Julian, but if this was one of his friends, he'd probably do the same.
