A/N: Hey guys! Thanks for the feedback on the last story :) This is the last in a trio of prompts sent to me by McGeeklover and it is Greg having an allergic reaction. Do you think we'll ever run out of ways to torture the poor guy? Hope you enjoy!

Summary – Greg has an allergic reaction and Nick hurries to bring him his medicine, will he make it before Greg takes a turn for the worst?

Allergic Reaction

Greg had been investigating a robbery in the home of an elderly woman; she was very sweet and kind, Greg couldn't understand why people would be so cruel as to prey on such a person. She'd had some very expensive jewellery and antiques stolen -things which belonged to her deceased husband; Greg promised her he wouldn't stop working until he'd found the culprits and returned everything which had been stolen.

After Greg was finished collecting evidence, he went to the kitchen where the old woman was sat at the table reading her book; Greg hadn't wanted to kick her out the house.

"Mrs Taylor I think I have everything I need now" the CSI said with a smile. "I'll be heading back to the lab; will you be alright until your daughter gets here?"

"Yes thank you, dear" Mrs Taylor smiled back at him "You're such a nice boy. Do stay and try a piece of my cake, I just took it out the oven, it's the least I could do to say thank you for your hard work"

"Oh, no Mrs Taylor, thank you, but I couldn't…" Greg started to politely decline.

"Nonsense dear, you deserve a break, and please, do call me Marie"

"Well…" Greg bit his lip thoughtfully; he wasn't supposed to hang around after all the evidence was collected, but he didn't want to leave the poor woman alone until her daughter arrived; so really, Greg found he didn't have the heart to say no "sure, cake would be lovely" he said with a smile.

"Good" Marie smiled and went to cut Greg a slice, handing it to him on a plate.

"It looks delicious" Greg said sincerely "tastes good too" he added after taking a bite.

For the next few minutes, Greg asked Marie about her family and was interested to learn she'd lived in Vegas all her life. After a little while though, Greg started to get an itchy feeling in his throat and his breathing started to sound a little scratchy.

"Are you alright, dear?" Marie asked when she noticed Greg massaging his throat a little and looking uncomfortable.

"Erm…was there Nutmeg in this cake?" Greg asked his voice slightly croaky; his throat was beginning to feel a little restricted.

"Yes…oh goodness, you're allergic aren't you?" Marie said worriedly.

Greg nodded and placed the plate down. "I'll be fine, I just need my medication" he said croakily and hurried out to his car.

The CSI had a stumble in his step and he started to feel a little sick and dizzy. His eyes were beginning to swell and his throat was becoming more and more closed up until the point he started to wheeze. Greg dived into his Denali and ransacked the glove compartment looking for his EpiPen, but a sense of fear started to consume him when he realised it wasn't there.

The one time I actually need it and I've left it in my stupid locker! Greg berated himself as he pulled out his mobile and hit the first number he thought of.

"Hello?" a Texan voice answered.

"Nick, are you still at the lab?" Greg asked hopefully.

"G? Yeah I am. What's wrong you sound terrible?" Nick asked concernedly.

"I don't have time to explain...but I'm having an allergic reaction…and I need my EpiPen but I left it in my locker….I need you to bring it to me…" Greg explained, but he needed to take frequent long and deep breaths. He also didn't want to risk driving back to the lab and fainting behind the wheel.

"Alright, alright I'll be there" Nick said with urgency in his voice and Greg could hear him open the locker door. "Got it, I know your scene, I'll be right there. Just hang on okay, you'll be fine"

"Thanks" Greg squeaked, and then hung up.

He rested his head back on the seat and took some more steady breaths as he closed his eyes. He was starting to feel sicker and dizzier by the second, and only took some comfort in knowing the house was only five minutes from the lab.

"Greg? Did you find it, dear?" the CSI turned to see a concerned Marie walking towards him.

Greg shook his head "Friend's…bringing it...for me"

"Alright dear, don't talk now" Marie encouraged "Just concentrate on breathing. I'm so sorry" she added with a guilty look "this is all my fault"

"No…mine…" Greg tried to reassure her "Shoulda…asked…"

"Ssh, you're going to be alright, sweetie" the elderly woman soothed as she sat in the seat next to Greg.

A couple of minutes later, and it was clear the reaction was really taking its toll on Greg's body. All around the CSI's eyes were swelling to he could barely open them anymore, his breaths were coming out in harsh rasps and a deep red rash was beginning to form on his arms.

Marie sat rubbing his back soothingly, contemplating calling an ambulance, when Greg suddenly threw the car door open and vomited harshly onto the road. He started choking and coughing from the lack of air going in and Marie pulled him back to lean against the seat as Greg continued to wheeze heavily; he felt so dizzy too.

"Don't worry; your friend will be here soon" Marie continued to sooth Greg; although she was getting more worried. Greg nodded weakly, and then very slowly, his head started to droop to one side and his eyes began to close "Greg? Greg, can you hear me?" the old woman asked tapping his cheek lightly but it was no use, the CSI had fainted and his breathing had become very shallow.

There was a sudden screech of tyres and Marie watched as a Denali – very much like the one she and Greg were currently sat him – ploughed around the corner and started heading towards them. She watched as the truck pulled over, and a frantic looking man ran over, gripping an EpiPen in his hand.

"G! C'mon, man" Nick exclaimed as he opened the car door and nudged his friend's shoulder, desperate for a response.

"I'm calling for an ambulance" Marie told him as she grabbed Greg's mobile which he'd left on the dash board.

"Greg, c'mon please don't do this to me" Nick pleaded; it was evident just from his voice he was sacred. He was so shocked by the sight of Greg's eyes so swollen and his arms covered in such a prominent rash; the man before him didn't even look like Greg anymore "I-I don't know what to do" Nick said to Marie once she'd got off the phone "D-do I give him an injection, I don't know where to give it though, what if I make him worse?" the Texan fretted.

"It's alright dear; the ambulance said they'd be here in less than five minutes" Marie reassured him "They just said to make sure to keep Greg's airway open, so let's take him out and put him in the recovery position, alright?"

"Yeah, yeah alright" Nick nodded; just glad someone was keeping a calm head in the situation.

"Can you lift him yourself, dear?" Marie asked "I'm afraid I won't be much help in that department"

"Oh yeah, he's a twig" Nick joked and the woman smiled. "Stay with me, G" the CSI whispered to his friend as he lifted Greg out of the car bridal style and then placed him down on Marie's front lawn where the old woman was stood.

After positioning Greg on the grass, Nick stroked the younger man's hair back and whispered words of comfort to him.

"He's a very good friend on yours?" Marie asked.

"Yeah, he's more like an annoying little brother" Nick said with a small smile "And I worry about him… "He added with a sigh. "How did the reaction start anyway?" the CSI asked with a frown.

"I'm afraid that's my fault" Marie confessed, and Nick realised the guilty look on her face which had always been there "I offered him some food, I should have asked if there was anything he was allergic too"

"And did Greg by any chance insist it was his fault?" Nick asked with a knowing smile. He wasn't mad; he knew it was an accident and he knew Greg would be okay.

"Yes, he did" Marie replied fiddling with her necklace nervously.

"Well, that's just Greggo for ya. He doesn't like to dish out the blame" Nick said looking down at the younger man with a sad smile "You're gunna be fine, I promise" he whispered to Greg, just wanting the younger man to hear him.

The ambulance finally arrived after what seemed like ages to Nick, and the paramedics immediately got to work opening Greg's airway and Nick handed over the younger CSIs medicine hoping it would help. The medic asked if Nick if he was coming with them and the Texan didn't need to be asked twice.

"Do let me know how he's getting on" Marie pleaded just before they left.

"I will" Nick smiled "and thank you for your help"

"It's my fault he's like this in the first place" the old woman remained insistent.

"Don't blame yourself, okay? Greg wouldn't want that" Nick reassured her.

Marie just nodded and watched as the medics slammed the door shut and the ambulance began to drive away.

Nick had been waiting impatiently for about half an hour or so as the doctors took care of Greg. The poor kid hadn't even looked like himself and Nick had never thought his allergy was that bad. Nick just wished he'd gotten there with Greg's medicine sooner, and then maybe the young man wouldn't have gotten so bad.

Finally, the doctor arrived to tell Nick that Greg was going to be fine, and the CSI let a great sigh of relief escape him. The doctor went on to explain Greg was sleeping, but they just wanted to keep him in overnight to make sure his airway had fully reopened. The doctor then led Nick to Greg's room so he could sit with him.

Nick smiled sadly at his younger friend lying still in the bed before him. The swelling around Greg's eyes and the rash on his arms had definitely gone down, and he was starting to look like the same crazy Greggo. There was a nasal cannula running around his face to help get the air in, but other than that Greg seemed to be breathing a lot steadier.

Nick sat down by Greg's bedside and rested his head on his fist as he waited for the younger man to wake up. Just as the Texan's eyes were about to droop close, a soft moan came from Greg's bed and he started moving around under the sheets.

"Greggo?" Nick asked, instantly more alert "C'mon, you can wake up now, I'm bored" he joked.

"Sorry for being such an inconvenience" Greg mumbled sarcastically, but he had a smirk on his lips.

"You sound awful" Nick commented.

"Your accent always makes you sound awful, I don't understand you half the time" Greg jibed back.

Nick rolled his eyes "I'm glad to see you're back to your annoying and slightly obnoxious self"

Greg smiled not very lucidly "You were worried about me and you know it"

Nick folded his arms defiantly "Was not"

"Was too"

"Was not!"

"Lies…"

"Fine!" Nick conceded, knowing Greg would never give in "I was worried…a little"

Greg smiled at him "Thanks, man"

"You're welcome" Nick smiled back.

There was a knock on the door and Catherine entered along with Sara, they smiled at the two CSIs and Catherine had a box in her hand.

"What you got there, Cath?" Nick asked.

"Well I know hospital food sucks so we brought something for Greg" she said and opened it to reveal a large cake.

Greg groaned in dismay and pulled the covers all the way up over his head. The others just looked awfully confused.
