"Hey, Whitehall!" Chase called out as he followed the younger man outside.

"I'm busy." Whitehall said without turning to look at him.

"Stay the hell away from, Park!" Chase said as he fell into step along side him.

"Mind your own business." Whitehall said as he stopped and looked down at Chase. "None of this concerns you."

"She's a friend of mine and you're scaring the hell out of her, so it is my concern." Chase replied through gritted teeth.

"Chase, get back inside." Foreman's voice broke the silence that had fallen between the two men.

"We're just talking." Chase lied.

"Get back inside, now." Foreman motioned to a security guard who stood just behind him. "Please escort Dr. Chase back inside, Henry."

"He should be escorting this creep off the grounds." Chase argued.

"Now, Chase!" Foreman stepped aside so that Henry the guard could take Chase by the arm. "We'll talk later." he whispered to Chase as he walked past.

Whitehall watched with a smile as Chase was led back into the hospital. That little man was really starting to get on his nerves. Why couldn't he just let Chi work on her own relationship? There had to be something going, regardless of what Chi told him. Even if Chi didn't have any interest in the Australian doctor, he felt that Chase might try to get in their way. He couldn't let that happen.

"I'm sorry about that, Mr. Whitehall." Foreman said once he made sure that Chase was back inside the hospital.

"It's fine." Whitehall said. "I need to get going now." he added as he turned to leave.

"Actually, Mr. Whitehall, I need to talk to you." Foreman stopped him. "I've been told that you've been harassing a member of my staff."

"I don't know why anyone would tell you that." Whitehall shrugged.

"I'm going to have to ask you to stay away from Princeton-Plainsboro." Foreman said. "Unless it's an absolute emergency of course."

"So, unless I'm knocking at death's door, or someone I know is, I can't come here for treatment?" Whitehall asked, not liking what he was hearing.

"Yes, I'm afraid so." Foreman nodded. "I have to make sure my staff feel safe and comfortable in their working environment. I'm sure you understand, Mr. Whitehall."

"Yeah, I do." Whitehall nodded. "So, unless there's an emergency, you won't see me here." he said with a smile before turning and leaving.

Foreman watched the young man leave and sighed in relief. If he hadn't come out when he had, he was sure that he would have been suspending Chase for assaulting Whitehall. He would have to do something with Chase to make sure he kept his temper in check.

Chase glanced into the team's conference room and saw that it was empty. No doubt the others were with their patient. He figured he should probably join them. Perhaps if he looked sufficiently busy, Foreman wouldn't feel the need to pull him aside and lecture him about his near run in with Whitehall. He knew that he shouldn't have gone after the man, but the look of fear on Park's face as she ran past the team in the hall, and the look of satisfaction on Whitehall's face as he watched her flee was more than Chase could take. He knew that if Foreman and that security guard hadn't shown up when they did, there would have been an altercation, one that Chase wasn't so sure he would have come away from without a great deal of bodily injury to himself. Whitehall was massive! He must be at least 6'3" and about 300 pounds. He knew Whitehall could easily take him in a fight, but the urge to punch the bastard was there all the same.

Chase was on his way to the patient's room when he saw Park slipping into the break room and decided to check on her. He wanted to make sure she was okay, and to see if he could convince her to head home for the rest of the day.

"Hey." he said as he poked his head around the door and looked around, making sure they were alone.

"Hey." she quietly replied as she made herself a cup of black tea.

"Are you okay?" he asked as he came to stand next to her, grabbing a coffee cup for himself.

"No, I'm totally freaked." she shook her head as she stared at the tea bag that bobbed up and down in her cup.

"I can understand that." Chase said as he picked up his cup, turned and leaned against the counter.

"Can you do something for me?" she asked, not taking her eyes from her tea.

"Sure."

"Don't talk to him again." she said bluntly. "Don't talk to him, don't go near him, don't even look at him."

"What?"

"He said that you told him to leave me alone." she finally tore her gaze from the tea and looked at him.

"Yeah, I did." he nodded. "I was hoping it might scare him off."

"It didn't." Park said. "It made him even more upset. Just don't go near him again."

"So, I'm supposed to stand by and watch you be tortured by this creep?" Chase asked, completely baffled.

"I don't want you getting hurt!" Park snapped. "Him being there every time I turn around is bad enough, but if he did something to you, or anyone, I wouldn't be able to handle that."

"He's not going to hurt me." Chase set his cup down and put his arm around her shoulder.

"You weren't in that elevator." she said quietly. "You didn't see the look in his eyes, or hear the tone of his voice, Chase." she looked up at him, tears threatening to fall despite he efforts to keep them from doing so. "I'm afraid he might do something to you."

"Okay. If it will make you feel better, I'll stay away from him." Chase sighed. "Unless he's near you, bothering you, then I'm going to step in."

"Just promise me, that unless it's some sort of emergency, you won't go anywhere near him and you won't have anything to do with him."

"Scout's honor." he smiled.

"Were you ever even a scout?" she asked skeptically.

"Well, not technically, no." he shook his head. "I was friends with a few boys who were."

"Then that doesn't really count."

"I promise." he said in all seriousness. "Unless it's a matter of life or death, I will not go anywhere near that man."

"Thank you." she gave a weak smile. "Can I say something without you laughing at me?" she asked.

"Depends on what it is." he replied honestly.

"Well, I'll go for it anyway." she took a deep breath. "You're my best friend." she blurted out without looking at him, feeling like a bit of an idiot as she said it.

"Let you in on a secret." he whispered as he leaned in close. "You're mine." he smiled.

"We should get back to work." Park laughed nervously.

"You sure you're up to it?" he asked. "You could head home. I don't think Foreman or House would mind."

"What would I tell my parents?" she asked as she took a swig of her cooling tea.

"Oh, you'd head to your parent's place?" Chase asked, a bit disappointed.

"Well, that's my home." she pointed out.

"You know, my landlord said I could get a roommate whenever I wanted." he said as he dumped his cooled coffee in the sink and rinsed the cup. "And having someone help pay rent and utilities wouldn't be the worst thing in the world."

"Robert Chase, are you saying you don't want me to leave?" Park asked with a smile.

"I'm saying, that you wanted to find your own place, have some privacy, and I wouldn't mind some company."

"You do live in a safe and quiet building, in a decent neighborhood." Park conceded.

"And you'd have an awesome roommate." he pointed out as he held the door open for her as they entered the hallway.

"You're sure about this?" she asked as they slowly made their way to the elevator. "You are taking into account a certain stalker, right?"

"Positive." he nodded.

"Okay." she said. "It's a deal, you've got yourself a roommate." she held out her hand for a handshake.

"Great." he laughed as he shook her hand.

He wasn't going to let her know that part of the reason he wanted her to be his roommate was because of that certain stalker. He felt better knowing where she was and that she was safe. At home and at work, Chase would be able to protect her.

"Finally decided to show up?" House asked Chase and Park stepped off the elevator.

"Sorry." they both said. "How's the patient?" Park asked.

"Not much of a change either way." Taub replied. "That could be good or bad, not sure yet."

"You're sure you're okay, Park?" Adams asked as she eyed her.

"Would it help if I said I was totally freaked and constantly looking over my shoulder?" Park asked.

"No, but it would be understandable." she replied.

"That reminds me." House said as he headed off to his office, the group following after him.

"What reminds you of what?" Taub asked as they filed into House's office.

"I got a little present for each of you." he said as he handed out small boxes.

"Why?" Chase asked as he cautiously inspected the box he held.

"Are you waiting for them to explode?" House asked.

"Kind of." Park nodded.

"Uh, that would have me sent back to prison." he pointed out. "Do you think I'd risk that just to prank you?"

"Kind of." Taub nodded.

"A giant jawbreaker?" Adams asked as she carefully opened the box.

"Silly putty." Taub said as he opened his.

"Hello Kitty confetti?" Chase stared at the small plastic bag in the box.

"A stun gun?" Park stared at the object before her. "Is it legal for any of us to have this?"

"I know of no law saying the average person on the street can't have one." House replied. "Then again, I know very little about the law." he added as he grabbed his backpack from the floor next to his desk and headed for the door.

"You're leaving?" Adams asked as she stared at Park's ''gift''.

"No change in the patient, and you all have my number in case there is one." he said.

"Will you answer the phone if we call?" Taub asked.

"I said you had my number, I never said I'd answer the phone should any of you call." House said as he left.

"He's a weird man." Taub said as he looked over to Park who was gingerly picking up the stun gun. "What are you going to do with that?"

"I have no idea." she shrugged. "Why would he give me something like this?"

"His own very unique way of saying he cares." Chase answered. "He won't say it with words..."

"But he'll say it with a potentially deadly weapon?" Adams shook her head.

"Like I said, his own very unique way." Chase replied.
