Casey sat on the couch in Kelly's apartment eating and flipping through the channels. He'd just swallowed a piece of toast when he heard a knock at the door. Knowing that Kelly wasn't expecting anyone, he turned the TV off and went to see what was going on.

He was definitely surprised.

"Voight!" Casey felt his eyes bulge at the sight of the sergeant standing on the stoop.

"Hey Matt," Hank said in what Casey guessed was Voight's casual manner, "How've you been?"

"Uh...fine, what're you doing here?" Casey asked.

"I came to see how you were doing," Voight said.

"Why?"

Voight looked at him.

"Because I know this is a difficult time for you," he answered.

"That's an understatement," Casey replied.

It was a few seconds before Casey had the presence of mind to hold the door open, "Sorry, come in."

"Where's Severide?" Hank asked as he stepped in to the apartment.

"On shift." Casey looked at the cop and asked him, "Can I talk to you?"

"Sure."

"You...you know what happened, don't you?"

Voight nodded. "I'm sorry, Matt."

"Who else knows? Tell me the truth."

"My guys, Severide, that's it."

"No one else?" Casey asked, fearing to hope.

"Trudy knows, but she's not going to tell Randy, your guys aren't going to find out from my guys, Matt, I can promise you that," Voight told him.

"Thanks," Casey said glumly.

Suddenly he couldn't stop fidgeting, he alternated between looking at Voight, or the floor, or around the room, trying to get up the nerve to say what was on his mind.

"Uh...Voight?"

"Yeah, Casey?"

Before Casey even realized what he was doing, he reached over and threw his arms around Voight and got out a very emotional, "Thank you..."

"For what?" Voight asked.

Casey took in a ragged breath and answered, "For staying with me at the hospital...I thought I was going to die, I wanted to die...I...when you took Kelly away, I knew what was going to happen, I knew you'd found out and were going to tell him."

"I figured," Voight said as he locked an arm around Casey's back to physically support the younger man, "I could tell you were terrified of something."

"I just knew when he came back...he'd hate me for what I let happen."

"We didn't know at the time what was going on, we found Gabby's phone and that filled in the blanks. He took it pretty hard."

Casey groaned.

"You got a good friend there, Casey."

Casey nodded and smiled in spite of himself. "I know." He pulled back and told Voight, "That's why I was scared to death when he left with you. I figured everything would go right out the window when he found out."

"He knows what happened to you wasn't your fault, Matt."

"He's told me," Casey said. "I've gone over the whole thing so many times since that night...how could I have been so stupid to let Gabby do that to me? I know better."

"Can you tell me when it all started?" Voight asked.

Casey sighed and ran his hands over his face. "I have to talk to you too about it now?"

Voight's face gave nothing away, nor did the tone of his voice, but he explained to Matt, "There's a chance Gabby was getting some of her stuff from other paramedics dealing meds out of their ambos and onto the streets, it's a possible drug ring we're investigating, so anything you can tell me would help a lot. If there are more people doing this, we gotta find out who and where they are so we can stop them."

Casey visibly cringed as he took this in. He sighed and gestured to the couch, "Okay...I'll...see what I can do..."

"I can appreciate how hard this is for you, Casey," Voight told him. "Just tell me what you can."

"That's the whole story as far as I can remember," Casey wrapped it up about an hour later. "You don't have to say it, I know I was an idiot."

Voight had listened to all the gory details, never interrupted, had not said a word. Now it was his turn to speak.

"Matt, Gabby was drugging you before you were even aware of it, you have no way of knowing what you were already on, how much of it, for how long, or if you were even in your right mind at the time."

Casey thought about that and sighed. "That would explain a few things." He wrapped his arms around himself and got out a weak laugh as he said, "Doesn't say much when the reason I thought I was out of my mind with love is because I was strung out and didn't know it."

"Gabby had you on more drugs than you knew about, and she was giving them to you more often than you knew about," Voight told him. "It's a miracle you're still alive, Casey."

"I know...doesn't feel like one though." Casey paused before he asked Voight, "Do I really have to go see a therapist and tell all this to someone else again?"

"You told me, you told Severide, I know that hasn't made it any easier, but what scares you about telling someone who has no personal stake in the matter?" Voight asked.

"I tried to go once last week, I couldn't...I just couldn't go in there and tell someone else what had happened."

"Anybody who's ever had to go to therapy understands that perfectly," Voight told him, "But Casey, the doc's there to help you, not judge you, and you may not believe it but they've easily seen people in far worse situations than you."

Casey looked at him and asked, "Do you think I need to see a shrink?"

"I'm not the best person to ask, Matt," Voight responded, "but I'll tell you this. If it had been Erin, I'd drag her to one kicking and screaming the whole way."

Casey laughed at his comment. Then he sighed and asked, "Does Antonio know?"

Voight nodded melancholically, "I told him. I figured he'd had enough time to mourn his sister that he should know the truth."

Casey grimaced. "Guess that settles it, he's not going to want to see me again."

"Not for a while," Voight answered. "Not until he can get his head wrapped around what happened. His issue isn't with you, Casey, it's that this was his little sister that did this, and he can't reconcile that fact with the woman he thought he knew. Until he can come to terms with what happened, I've taken his badge, I can't have him working under me for the time being with this eating him up. And him I did drag to a therapist kicking and screaming so he can deal with it."

That revelation made the corners of Casey's mouth turn upward in something almost resembling a smile.

"Thanks for stopping by, Hank, I really do appreciate it."

"No problem, Casey," Voight replied as he stood up. "Good to see you're doing so well."

"Hank," Casey thought of something and sheepishly told him, "I'm sorry I threw up on you."

That comment drew a loud sudden laugh from the Intelligence sergeant, who responded, "Don't worry about it, Casey, this line of work, we all get puked on at some time."

"Don't I know it? ...Hank," Casey called to the cop just as he reached the door. Hesitantly he forced himself to ask the question weighing heavily on his mind.

"If I would've come to you, and told you what was going on...would you have believed me?"

Voight looked at him for a minute and finally answered, "Guys don't make false rape claims against their wives. Yeah, I'd believe you, and I would've come here, and searched the apartment, found the drugs, and the videos, and I would've locked Gabby up, her brother working for me be damned."

Casey squeezed his eyes shut and groaned. After the fact it all seemed so simple. Why hadn't he just done it when he had the chance? Why...

"Hey," Casey felt a set of hands on his shoulders, he opened his eyes and saw Voight standing right in front of him, "it's over, Casey. That's what you got to remember, it's over. You're gonna be alright."

Severide was having a hell of a time balancing his focus on the job and the inevitable inability to not worry about what Casey was doing home by himself. He'd managed to keep his head on the call they just returned from, as he wrote up his incident report he found his attention wavering again. the knock on his door brought him back to the here and now. He turned in his chair to see who it was, and he felt his eyes bug out.

"Voight," he said in surprise as the cop entered his quarters. "What're you doing here?"

"Heard you were back on the job, how's Casey holding up?" Voight asked as he closed the door behind him.

It took Kelly a few seconds to recover from his shock and he answered, "Fine...what're you doing here?"

"Thought you might like an update," Hank answered.

"On what?"

"We've gotten the names of two paramedics from neighboring ambo companies we think are dealing their inventory to people on the street, could be how Gabby got some of the drugs she was slipping Matt, kept her off the radar."

Kelly tried to take that information in but he felt like something was missing.

"So now what?" he asked.

"We're going to set up a buy with them and bust their asses," Hank answered. "These people are no different than the dealers on the street corners, and we are gonna take them out."

Kelly nodded, "I guess that's something." He tapped his pen against the desktop and said to Voight, "Can I ask you a question? Were we all blind to what was going on, or just stupid? How did we miss this? I mean...what would possess Gabby to do what she did?"

"There's no easy answer to that, Kelly. It's the same with a lot of professions, people take advantage of the position their job gives them, to get away with anything that comes to mind."

Kelly shot a knowing glance at him and responded, "Guess I asked the right person on that one."

"I crossed a line to try and save my son, don't even think of putting me in the same boat as that woman," Voight warned him.

"Sorry...I just...I can't figure this out, was Gabby always like this and we just couldn't see it? Or did something make her the way she was?"

Voight shook his head, "Asking the wrong person, I just bust them, I don't diagnose them."

"There had to be something, why couldn't we see what was happening?' Kelly asked.

"Because neither of them wanted anyone to see what was happening," Voight answered. "Gabby was good at covering her tracks, Casey is good at shutting everybody out when something's wrong."

"Yeah but we can still tell when something is wrong," Severide responded.

Voight calmly pointed out, "This hurt him worse than anything before in his life, it makes sense he went to greater measures to hide it. What his own wife put him through, nobody should have to live with betrayal like that."

Kelly couldn't bring himself to form any words to respond, but he agreed.
