Unexpected Reaction

(I rolled two requests into one, but the gist of this one is that Hailey accidentally eats something she's allergic to, but the team didn't know she was allergic to it and the reaction completely catches them off guard; set season 7)

"We got the camera footage and a dozen cupcakes, the shop owner would not let us leave without them. She was also very appreciative of our work," Vanessa said, walking up the stairs with Kevin.

"Sweet!" Adam clapped his hands together and took the box from Vanessa, setting it on a desk.

"Get the footage going first!" Voight ordered from his office.

"Yes sir," Kevin got it up and going while they all grabbed a cupcake.

Hailey grabbed a chocolate one and sat down to observe the footage with the others. She took one bite and noticed the icing wasn't plain chocolate, but she couldn't tell what it was.

"This is amazing! Nutella for frosting is genius!" Kim said, and Hailey suddenly started coughing.

"Hail?" She looked at the blonde as Vanessa's eyes widened and she ran to the locker room.

"Nutella is the one with hazelnut, right?" Hailey coughed.

"Yeah, why?" Jay asked.

"I'm allergic," Hailey gasped, standing up and backing away. She was looking for water.

"Hailey, how serious of a reaction are we talking?" Kevin asked as Jay grabbed a water and handed it to Hailey.

"Bad," she coughed before taking a sip of water.

"Where's your epi-" Jay couldn't finish the question before Hailey suddenly threw up on him.

"Crap," Kim grabbed Hailey's hair as Kevin grabbed a trash can and Adam yelled for Voight to call 911.

"No, drive me," Hailey said.

"Fine," Adam told Voight what was going on.

Vanessa suddenly appeared. "I have her epi pen," she said, taking the cap off.

"Okay, Hailey, can we lay you down or will you throw up again?" Kim asked.

Hailey was gasping for air as she heaved again, tears rolling down her cheeks. "Vanessa, just do it," Vanessa injected Hailey's leg with the epi pen and they helped Hailey sit in a chair, the trash can still infront of her.

"Hailey, can you breathe better?" Jay asked, trying to ignore the fact that he was covered in her vomit.

"A l-little," she gasped. "I'm sorry I threw up on you," she was absolutely mortified.

"No, hey, I'm not worried about that. It's okay, you couldn't control it. I'm more worried about you," Jay said, rubbing her leg.

Hailey nodded and coughed, throwing up again. A rash was breaking out around her mouth as well.

"Jay, go change, Adam, clean this up. Hailey, we're going to get you downstairs and into a car," Kim said, trying to keep Hailey calm.

Hailey nodded again, still coughing and having a little trouble breathing. "I called Med, they know you're coming. Rojas, take her, Atwater, ride with Halstead to bring Vanessa back in a few," Voight instructed.

They jumped into action and Kevin carried Hailey to her car, putting her in the passenger seat with a sack. Vanessa turned the sirens on and pulled out, rushing to Med with her room mate.

"Hailey, how are you doing?" She asked.

"It hurts," Hailey coughed.

"We're almost there," Vanessa reassured her.
