He perked his head up from the table and turned to face her. She looked like a deer caught in headlights.

"S-Sorry." she stumbled "I didn't know anyone else was awake."

He cleared his throat uncomfortably. "It's fine, I couldn't sleep."

"Me neither," Sylvie admitted

She walked over grabbing a seat across from him.

She felt calmer when Matt was around, not that she would ever admit it. He had such kind eyes and a smile that could melt your heart. Nothing like Mark. She knew she felt something for him, something more than just a professional relationship, more than a friendship. Her mind shot back to Gabby. Right. She reminded herself that he was off-limits.

Matt looked up from the book he was reading, closing it and focusing his attention on Sylvie. He scanned her face, the dark bruise on her forehead more obvious.

"Sylvie, what's going on?" he asked. "You've been acting weird today, distraught, distant. And the bruise on your head that's "fine" clearly isn't. So what's going on?"

Sylvie sucked in a breath at Casey's sudden outburst and subconsciously fidgeted with a hair tie on her wrist.

Her eyes dropped down to the table. "It's nothing, I just hit my head on my bedpost, you know how clumsy I am." she tried to fake a laugh.

Casey still wasn't convinced but he could sense the hesitation coming from his friend and decided it was best to leave it alone. For now.

Before the silence set in, a call came onto the speaker.

-AMBO 61, PERSON IN DISTRESS, 9120 SOUTH KEELER AVENUE-

Sylvie nearly jumped out of her skin at the noise, catching Casey's look of concern. She rose from her seat at the table, painfully running to the ambo.

At the scene, Foster and Brett met a middle-aged man at the top of a flight of stairs. Setting the backboard down, Foster lifted the man and set him down.

Sylvie attempted to strap the man down but he awoke and in a state of panic began to flail his arms. He sent an elbow behind him, hitting Sylvie square in the head. Her entire body began to radiate pain as she fell backward, just missing the bottom step. She hit the ground and her plane of view went fuzzy, and then dark.

The man was there again. Mark. Tall, brooding, towering over her. She suddenly felt so small and weak, sinking back into the floor. She felt water lapping slightly at her feet, sending painful tingles up through her legs and waist.

Cold water seeped through her blouse, drenching her body.

Light started to seep in and Sylvie opened her eyes. Where was she? This wasn't her apartment?

Standing above her was the one and only Kelly Severide. He was shaking her awake while Casey kneeled on the other side of her.

She tried to sit up, but the blaring light sent her into a whirl as she tried to steady herself. She fell back again, only to be caught by Caseys' strong hands.

"What happened?" she was able to rasp out.

Casey swallowed deeply and she swore she saw a little relief in his eyes. "You were attacked on a call, I think you hit your head pretty hard." He helped her up and sat her on a step.

Sylvie shook her head groggily but was met with shooting pains down her neck and back. Her eyes were watering and she attempted to avoid eye contact with her teammates and sat her head on her knees.

"We need to get you checked out Sylvie." Severide sighed "Make sure you don't have a concussion."

Although fully convinced she indeed did have a concussion, she couldn't risk a doctor finding the bruises on her body. The firehouse was particularly close with a lot of the doctors at med and knew that they would be at liberty to inform her employers of her injuries.

Panic filled her eyes and she shook her head "No, I'm fine, really. I don't need to get checked out, it's just a small bruise."

Casey and Severide shared an unconvinced glare and turned back to face Brett, helping her to her feet.

"I'm not asking Brett, go get checked out, take Foster with you."
