Brass arrives on the scene immediately looking for the bomb squad captain. Brass sees Charlie and walks towards him yelling, "What the hell happened Charlie? How could you send CSI in with an active device still in the building?"

Charlie replies, "We saw no active devices on our initial walkthrough and called it clear."

Brass still yelling, "Initial walkthrough? Is that how you operate? Oh send them in we'll do another walkthrough if something happens? You know what I don't care, where are my guys?" Charlie points to the medical squad. "Charlie you better hope they are ok. As far as I'm concerned you're fucking fired, get the hell outta my face and off this crime scene!"

Brass walks over towards the medical squad and sees Greg on a stretcher and appears to be unconscious as they are loading him in the ambulance. Brass continues walking toward the other medical squad and sees them getting ready to load Mark into the ambulance, Brass notices that Mark is conscious and says to the EMTs, "Hey fellas hold up for a second. Mark how are you feeling buddy?"

Mark replies a little irritated, "I'm fine I'm pretty sure it's just cuts and bruising, but they are insisting I have to stay overnight for observation. The hell with that this is my crime scene I want back in!"

Brass replies, "Come on Mark, buddy the department needs them to check you out. Come on man you're too valuable to us for us to let you go home and something happen later. I'll tell you what I'll get you out of there as fast as I can. I myself will come down to take your statement and I will see who I can get from CSI to come down I'm sure they will want to talk to you as well. I saw Greg was unconscious did you see what happened?"

Mark much calmer now says, "No he was behind me. We were running toward the door and about 20 feet or so from the door that's when it went off and threw Greg and I out of the building."

Brass nods and pats Mark and says, "Ok I'll see you soon."

In Warrick's SUV …

Catherine says, "Warrick, drive me to Desert Springs. I'll call Grissom and let him know I want to handle the questions and collection of any evidence at the hospital. I can't work on that crime scene not knowing what's going on with Mark."

Warrick says, "Ok," and drives towards Desert Springs.

Catherine takes out her phone and dials Grissom, "Gil, its Catherine, Warrick is dropping me off at Desert Springs, I want to be in charge of any questioning or collection at the hospital. I'll send him to the scene to assist."

Gil responds, "Alright sounds good. I'll keep you posted on anything we find here and join you at some point to check on the guys."

Warrick looks over at Catherine and says, "I know this is probably a stupid question, but how are you?"

Catherine let's out a huge sigh and says, "I honestly don't know. I just know I can't be of any use at that scene not knowing if Mark's ok. I am also so confused. If something happens to Mark, it's just not fair to think I could get something so great and have it taken away." Catherine starts to cry.

Warrick notices her tears and rubs her shoulder and says, "Cath don't think like that. Mark is a tough guy I just know it. I'm sure he'll come out of this ok."

Catherine looks at Warrick and says, "Thanks."

Warrick pulls up at the drop off zone at the ER and asks, "Are you sure you don't want me to come in for a bit and see what's going on?"

Catherine says, "I appreciate the offer Warrick, but you know as much as I do that they need as many people as possible on that scene."

Warrick replies, "Ok, I will call you later and try to stop by."

Catherine gets out of the car taking her kit with her and waves at Warrick as he drives off. Catherine walks into the ER and walks to the nurse's station. Catherine looks at the nurse and says, "Hello I'm Catherine Willows with the Las Vegas Crime Lab I'm looking for either Greg Sanders or Mark Anderson."

The nurse says, "Hold on just a second Officer Willows let me check the computer. I show that Greg Sanders is in surgery …"

Catherine interrupts the nurse and asks, "Does it say why Greg is in surgery?"

The nurse replies, "Let me pull up the notes. Ah yes it says that there was a piece of metal stuck in his back that they are removing."

Catherine asks, "What about Mark Anderson?"

The nurse again looks the information up on her computer and says, "Actually Mr. Anderson is right down the hall, his injuries were less severe. Looks like mostly cuts and bruises, but as standard procedure he will be held overnight for observation. Would you like me to take you to Mr. Anderson?"

Catherine replies, "Yes, please."

The nurse gets up from her seat and says, "Follow me please."

Catherine follows the nurse down the hall and into a room on the right.

The nurse says, "Mr. Anderson there's someone here from the Crime Lab to see you."

Catherine walks in and sees Mark and feels a rush of relief as she sees he looks mostly ok.

Mark says, "Thank you."

As the nurse leaves she turns to Catherine and asks, "Officer Willows would you like me to inform you when Mr. Sanders gets out of surgery?"

Catherine replies, "Yes that would be great. You can call me Catherine by the way."

The nurse nods and says, "You can call me Sandy. I will let you know when I have more information on Mr. Sanders." Nurse Sandy walks out of the room leaving Catherine and Mark alone.

Catherine immediately rushes to Mark's bedside and hugs him really tight and starts to cry. Mark says, "Honey I'm fine. Mostly just cuts and bruises, I got lucky."

Catherine kisses Mark and then scoots a chair to his bedside and sits next to him holding his hand. She says, "When I heard the 911 assistance call go out on the radio I was so scared. I was afraid I'd lost you."

Mark smiles and says, "You're not going to get rid of me that easy."

Catherine shakes her head, slaps his hand and says, "I can see you're going to be fine, Mr. Comedy."

Mark asks, "Did they tell you what was going on with Greg? I've gotten zero information on him since I came in."

Catherine nods and replies, "The nurse told me there was a piece of metal stuck in his back that they have to remove."

Mark looks at her in a serious manner and says, "He was unconscious after the explosion. I'm really concerned."

Catherine rubs his hand and says, "Me too. Not to sound all official or anything but tell me everything that happened."

Mark thinks and says, "Greg and I arrived on the scene and we were told by the bomb squad captain that they found nothing on their initial walkthrough and they said the building was clear and we could go in. They said if we saw anything suspicious to let them know and they would check it out. Greg and I entered the building and turned on our flashlights and started assessing the scene. Greg found the area where the blast came from and I stopped to take some pictures. Greg walked away continuing to assess the scene. He saw something and called me over to check it out. I saw this flashing light, which I was assuming what Greg was talking about and then this beeping started. I told Greg to run and I looked back to see he was following me. We got about 20 feet from the door and it went off and Greg and I were thrown from the building and landed on the ground."

Catherine asks, "So the beeping started when you walked up to Greg?"

Mark replies, "Yes, I'm not sure if it was set up to go off by motion or maybe some kind of weight sensor on the ground. But either way I can't believe a) it wasn't destroyed in the initial explosion and b) that the bomb squad overlooked it."

Catherine replies, "Yeah that's pretty unbelievable, but trust me if anything is to be found the team will figure it out."

Mark looks at Catherine and asks, "So how did you get this duty?"

Catherine says, "I just knew I couldn't be at the crime scene. I would be of no use to anyone wondering about you. So I called Gil and told him this is where I would be to ask questions and collect any evidence."

Mark asks, "Do we have some explaining to do with Bossman yet?"

Catherine says, "I'm not sure. We should probably talk about that at some point. Right now I'm going to find Nurse Sandy and find out what they did with your clothes, as they are evidence. I do have to do some work."

Catherine walks out of Mark's room and back down to the nurse's station where she spots Sandy. She says, "Sandy do you have Mark Anderson's clothes by chance? We need to bag them as evidence."

Sandy says, "Follow me back to Mr. Anderson's room they should be in there."

Catherine follows Sandy back to Mark's room. Sandy picks up a bag and hands it to Catherine and says, "It should all be in here Officer Willows … I mean Catherine. If you need anything else just let me know. I will go check on Mr. Sanders progress in surgery and get back with you."

Catherine smiles at Sandy and says, "Thanks so much."

Sandy replies, "No thank you for everything you do to keep the community safe." Sandy leaves the room again leaving Catherine and Mark alone.

Catherine's phone rings and she answers, "Willows."

Sara is on the other end and says, "Hey Cath its Sara. I'm on my way to the hospital. I'm going to take Mark and Greg's clothes into the lab if you have them."

Catherine replies, "I am in Mark's room now, the nurse just gave me his. I will try and track Greg's down he was taken to surgery."

Sara says, "Greg's in surgery? Why?"

Catherine says, "The nurse I spoke with said the notes said there was a piece of metal stuck in his back that they are removing. She's supposed to be checking on his condition, I will see if she can get me Greg's clothes."

Sara says, "How's Mark?"

Catherine laughs and says, "He's fine just some cuts and bruises, he was pretty lucky. He has to stay overnight for observation, which he is not happy about; I can tell he really wants to be back at the crime scene. He's also joking around and being his smart ass self, so I'd say he's in good spirits."

Sara laughs and says, "Well that's good. Where is his room?"

Catherine responds, "He's in the ER just down from the nurse's station."

Sara says, "Alright Cath see you soon."

Catherine leaves to find Nurse Sandy again and asks, "Sandy can I ask you a favor?"

Sandy says, "Of course. What is it?"

Catherine says, "Greg Sanders clothes are evidence too. I need to find them, someone from the lab is on the way to pick them up."

Sandy says, "Sure I'll go track them down and bring them to Mark's room."

A few hours later …

Catherine is still in Mark's room. He is sleeping; she is flipping through the channels trying to find something to keep her attention, but not having much luck. A few moments later a white haired Dr. walks in the room and asks, "Officer Willows?"

Catherine stands up and replies, "Yes, I'm Catherine Willows."

The Dr. introduces himself as Dr. Klein. "I operated on Greg Sanders and was told you wanted updated on his condition and that you would be needing the metal shrapnel we removed from his back as evidence." Dr. Klein hands her a bag with the metal. "Mr. Sanders has not woken up yet. It may be a while. He took quite a blow to the head, which made him unconscious before he got here. We're monitoring the situation and hope to have more information soon. As for the metal we removed there was no muscle or nerve damage so he should make a full recovery as long as he wakes up from the coma."

Catherine says, "Thank you Dr."

She pulls out her phone to call Gil not quite sure how to break the news.
