The next morning Gil woke up long before Greg and had made breakfast. Sarah had come bye and brought some juice, "So is he up yet?" she asked.

"Not to my knowledge, but I try to make it a rule not to go in his room unless invited. By the way, how is the case in his building going?" he asked as he plated the pairs breakfast.

"The victim was found in the apartment just below Greg's, arson. Several gas cans spread around and matches. The owner on the apartment still hasn't be located, so he is currently the prime suspect." After taking a bite of toast, she said, "What's really strange is that it looks like whom ever lit the fire was trying to make it reach Greg's apartment."

Gil looked shocked and scared, remembering what Greg had said about his stepfather. "You don't think Greg was the real target do you?"

About that time Greg came stumbling out of his room, and feel into a chair at the table, "Morning Sarah, what are you doing here?"

"Greg, who lives below you?" Gil asked.

"Good morning to you too." Greg said, and then thinking, "I don't know, I mean I pretty much thought that unit was empty until 2 days ago. Why?"

"No reason." He said.

"Just so you know, you're a terrible liar." Greg said after stabbing some eggs and eating them, "So tell me what's up, I'm still a CSI remember."

'But you're also my little boy.' Grissom thought to his self.

"The crime scene is the apartment below you. Confirmed arson." Sarah said flatly.

Later that night at the lab Greg was searching for a match on the prints found on several matchbooks at the crime scene. He got a hit, to the stomach. David Stevens, his stepfather, had come back to complete the job he swore to do so many years ago….

"I'll kill you, you little bastard. Maybe no today, but I'll kill you. You ruined everything and you're going to pay." David said as Greg and his mother drove away from the house in which 3 years of constant abuse had taken place.

"Greg?" Nick looked in the door, "Greg are you ok? You look like you've seen a ghost." Before Nick could say anything else Greg fainted and landed on the ground with a thud. Rushing to his side Nick tried to coax him up, "Come on Greg, wakey wakey."

Grissom and Warrick had been walking by when they noticed Nick and Greg on the ground, "What's going on?" Grissom demanded.

"I'm not sure, I came in and Greg didn't look so hot; next thing I know he is face down on the floor."

Grissom rushed to his son's side and held on to him, "Come on Greg, time to wake up, you can do it." Greg slowly came to and looked at everyone staring back at him, "Greg, what happened?"

Greg couldn't say and just burst into tears, "Guys, Catherine is working on a crime scene, go see if she needs any back up." Grissom held on to Greg even tighter, "Come on Greg, and tell me what happened." Greg couldn't muster any words but pointed to the computer, and there was a picture of the man who had harmed him those many years ago. Trying to sooth him Grissom changed his tone, "Its ok Greg, nothing is going to happen to you, I'm here, I'll protect you."

The team made Greg's case top priority. Greg had seemingly reverted back to almost an infant, refusing to be anywhere Grissom wasn't. "I'm worried Sarah."

"I know." She tried to comfort him.

"What if something happens to him? What if this bastard gets my son?" he asked in an uncharacteristically timid voice.

"No one is going to mess with Greg. He is our safe little lab rat. I promise we are going to catch this ass and send him straight to jail; where he will rightfully become someone large man named Bubba's girlfriend." She assured him. This made Grissom smile as he went in to kiss her.

Mid-kiss Brass came in Grissom's office, "We've found him, but I'm afraid there is a problem." Brass told Grissom of how the suspect had checked himself into a mental facility to hide out.

"This is ridiculous, why can't someone just go pick his sorry ass up?" Gil demanded.

"We are doing the best we can, but the doctors are refusing to relinquish him into our custody." Brass explained.

Sarah had to answer a call about a dead body a few blocks away, and Jim and Gil were now alone, "Look, I know what its like. Worrying about your kid. All I ever do with Ellie is worry. I love her to no end, but I swear she'll cause me to have a heart attack, you've got to trust yourself though, trust that you won't let anything happen to your kid. We're going to get this guy, and as soon as we do, you'll be the first to know. I promise."

"Thanks Jim. I just feel so bad, I wasn't able to protect him from this guy before because I didn't know about my son or his abuser, and then he has been living right below him for months planning out killing him. I feel like such a failure for not noticing earlier." Grissom confessed.

"I know what you mean, but hey, lots of uncertainty comes with the job. Welcome to fatherhood." Brass said as he left.

Soon there after, Greg popped his head in the door. "So what's going on, Dad?"

That one really hit Gil, Greg didn't call him Dad often and he felt like a total failure of a father seeing as Greg was so close to getting hurt again. "We found David." He said flatly, "But there is a hold up in the process, but don't worry Greg, you're going to be ok. And you're safe."

3 days later, David was in interrogation, Grissom, Brass, and Greg all walked in, "You bastard. I'm gonna get your ass, mark my words boy, you're as good as dead." He said in an icy tone that made everyone shiver.

Greg looked like he was going to ball up at any moment and start crying, Grissom gave him a look, and Greg felt safe enough to stay in the room. "Unfortunately, Mr. Stevens, you won't be getting the chance. Seeing as you attempted to kill Greg, set fire to a building, and took money out of 7 different accounts, none of which have your name on it. You sir, are going to jail for a very long time."

David laughed, "You think this pathetic piece of shit will ever squeal on me? Ha, he knows his place, in a coffin." Greg could feel himself getting smaller and smaller, but after a quick reassuring glance from Grissom felt a little safer.

David got out of his chair and came after Greg; Grissom knocked him out with a single punch to the jaw. "Come on Greg, let's go home. Jim can you clean this up?"

Brass nodded, "I'll take him down now, and make sure he never sees the light of day again with out several bars chopping it to pieces."

Grissom and Greg got in the car and drove back to Grissom's apartment, where Sarah was waiting for Gil, who opened the door to find her wearing a very small nightie, Grissom's jaw dropped, this stunningly beautiful woman was all his. "Greg, why don't you go to bed?" he said in a daze.

"But I'm not even tired…"Greg started but Grissom cut him off and pointed toward his room. Greg went like a small child who had gotten in trouble.

Sarah and Gil went off to his room and enjoyed their evening together. The next morning, Greg knocked on the door, in a sarcastic tone, "Does this mean I have to call Sarah 'Mom' now?" he said with a laugh.
