Jack and D were driving back to the bullpen when they were interrupted by D's cell going off.

"Gans. OK. We're on our way," he said, then turned to Jack. "Tara's got an address for Nelson's friends." D gave Jack the address as Jack turned the corner. When they got to the address, they parked and got out. When they knocked on the door, one of the friends came to the door. Jack showed him a picture of Marc Nelson and asked if he knew him.

"Yeah, we work out at the gym together sometimes," the guy replied.

Jack and D continued to talk to the guy. They managed to get him to tell him where this gym was and more information about the gym. They went there and found out the names of people Marc Nelson regularly works out with.

That afternoon, Jack and D filled Tara, Myles, Luc and Sue in on what they'd found out.

"I looked up the names they'd found. None of them came up on the computer except one. One came up as being in a gang," said Tara.

"Would he be able to get Nelson the dynamite?" asked Sue.

"Possibly. But he'd be more likely to steal it," said Jack.

Their conversation was interrupted by Howie appearing in the doorway.

"Hi, Howie! What's up? I said we'd let you know if anything else develops," said Sue, when Levi informed her of Howie's presence.

"Well, you know me. I have to do my part. I've got a tape of Nelson. I followed him to the warehouse, where he met a friend. I think you'll find it interesting."

"I'm sure we will. Thanks, Howie," said Sue.

"I've got to go, but I just thought I'd drop it off," said Howie, turning to leave.

The next morning around 8:30 am, Lucy answered the phone in the bullpen.

"Rotor,"

"Lucy? This is Donna."

"Hey, Donna, what's up?" asked Lucy.

"I'm afraid something's wrong with D. He's come down with some sort of flu or something. He won't be coming into work today," said Donna.

"That's too bad. I'll be sure to tell everyone. I hope he gets better soon," said Lucy.

"Lucy?" asked Donna, just as Lucy was about to hang up.

"Yeah?"

"D mentioned that he and Jack went to visit Bobby yesterday. I'm thinking maybe Bobby's contagious, so if Jack comes to work…"

"I'll call Jack. Thanks for calling."

Lucy hung up the phone then called Jack's cell number.

"This is Jack," came the reply.

"Jack, it's Lucy. Have you left yet?" asked Lucy.

"No, I'm just leaving. There a problem?"

"Yeah, you need to stay home today."

"WHAT!" Jack almost screamed into the phone. "What's going on?"

"I know it sounds nuts, but just listen. D's sick. You guys both went to see Bobby yesterday and we think Bobby's contagious. We don't want you getting us all sick," said Lucy, smiling at Jack's reaction.

"OK. You'll tell Garrett? Maybe he'll send someone in to help with the case."

"Alright. Try not to get sick, OK? Take it easy today," said Lucy.

"Mhmm – uh, Luce, have someone send me files or anything I can do to help," said Jack, sitting down as he was still in shock a bit.

"OK," said Lucy as they both hung up their phones.

Lucy walked over to Sue and tapped her on the shoulder.

"Everyone, listen up. It's just us today. D's sick and Jack's staying home so we don't all get sick, since both he and D went to visit Bobby yesterday," Lucy told everyone.

Tara smiled and said, "Well, then, should be a quiet day."

"Can you come with me to Garrett's office?" asked Lucy to Sue.

Sue nodded as they got up to leave.

At Jack's place, he sat down on the couch, stunned. He felt lost and helpless. He turned on the TV, flipped through a few channels for a bit, then decided he might as well do something useful and went to wash the dishes he'd left from breakfast. But as he turned on the water, his thoughts turned toward Sue. He tried to imagine what it would be like not to hear the water running. He thought more about Sue and how life must be so different for her. But it wasn't long before his thoughts drifted towards more than just logistics but towards what it might be like to live with her or even to be married to her. Did he really love her or just admire her determination and courage? However, his thoughts were disrupted by the water soaking his shirt. He realized he'd let the whole sink fill with water so he turned the water off and finished the dishes. When he was done, he turned on his computer. Seeing that Tara hadn't sent him anything yet, he decided to pick up the phone and see how Bobby was doing.

"Hello?" Bobby groggily answered.

"I'm glad you decided to actually answer this time. How are you feeling?" asked Jack.

"A bit better, thanks. I think I'm done throwing up. Hey, are you at home?" asked Bobby, noticing the background of the call was quiet.

"Yeah, apparently D's sick, too, so since we both came to visit you and he got sick, I could pass on the germs to the rest of them. So I'm here."

"Wow, Sparky, I'm that bad, eh?"

"Well…"

"Whatever. You bored yet?"

"Not yet, but it probably won't take too long. It's pretty quiet around here," said Jack.

"Well, now you can relate to someone else we know," commented Bobby.

"I was thinking about that, earlier, actually. I can't even imagine what it would be like: not hearing water running, phone ringing, or even people walking."

"She's never known anything else, though."

"That's true. Well, get some rest. Hopefully, things can get back to normal soon," said Jack, trying to bring his thoughts back to reality.

"Hope so, too. See ya.

"See ya."
