Walking with her fiancé into the hospital's physical therapy room, Emily's dark eyes darted from patient to patient she saw. One man was trying to grasp a pencil - Emily recognized him from her first trip to the hospital that year, his entire right side almost paralyzed - another trying to steady himself on his one foot and new prosthetic, and a young girl bouncing on an exercise ball.

Her hand immediately shot out to grab onto her fiancé's.

"You ok?" Hotch stopped his stride and stood in front of the younger woman. Pushing one of her curls from her eyes, he fixed it behind her ear. "We can wait a few more minutes before you start."

The amputee held her breath, watching as the little girl from the exercise ball walked toward them.

"Hi!" The little girl with flowing blond hair looked to the boy by the other patient's side. "I'm Haddie," she grinned. "Is this your mommy?"

Jack hid behind Emily's leg.

Holding out her hand to the woman in front of her, the seven year old lit up with a smile. "Dr. Jenny is really fun." Once the stunned woman shook her hand, Haddie's blue eyes looked over to the brunette's obvious missing arm. "What happened?"

"A car accident." Emily let her voice soften as she slowly followed the little girl over to the television she had been watching a moment ago. "What about you?" As the seven year old sat back down on the ball, the FBI agent could see that she wore a curved piece of metal as a left foot.

"My mommy said I was born with it," she nodded. "Dr. Jenny gave me a blade!"

"That I did."

Emily turned her head to see the unfamiliar woman stepping toward the resting section. Standing from her seat, the FBI agent gave her hand to the younger woman. "Emily Prentiss."

"Jennifer Keeler," she smiled. "You're Chris Kard's patient," the doctor nodded. "I'm going to get you started because he's not here today. Is that ok?"

"It is."

Smiling to the little girl in the room, Jennifer sat herself down. "Haddie, are you happy with today?"

The seven year old girl blushed at the smile she was given. "Yup!"

"Ok, then I'll see you on Friday." Waiting until the little girl ran out of the room to meet her parents outside, the physical therapist looked over to her new patient. "Haddie has been with us her entire life," she stated, standing from her chair. "Usually those 'blades' are used for runners when their feet have been amputated, but she wasn't comfortable with our normal prosthetic."

Emily nodded. "Is that usual?" Seeing the doctor's confusion, Emily shrugged. "To not feel comfortable in them?"

Jennifer was quick to nod her head. "Everyone feels different in them. The prosthetic is custom made for you and your amputation. It can be made out of plastic, a mixture of plastic and silicone, and sometimes people choose not to have a prosthetic at all."

Seeing the doctor eyeing the two she'd brought in with her, Emily made her way over to her family. "This is Aaron," she smiled, gesturing to her fiancé, "and this is Jack."

"It's so nice to meet you, Jack," Jennifer grinned. Watching as he slowly brought himself out from behind his father's leg, the therapist pointed over to the television. "We have some games for you to play while I help your mom for a little while. Is that ok?"

Jack looked over to the woman his father was marrying for an affirmative nod before he took off.

Hotch stuck his hand out to finally shake that of the younger woman. "Aaron Hotchner. I hope you don't mind but my son and I will be joining Emily here every day."

"Every day?"

Emily let her fiancé take her hand in his as he explained their situation to her doctor.

Once the older man had finished, the doctor ended up back in a smile. "Alright. Well I'll be working with Emily for the better part of an hour. If you want to sit and watch then that's fine, but if you want to go over and play with your son then that's fine too."

The FBI agent followed the doctor over to the center of the room, her hand reaching out and grabbing one of the parallel bars when she felt herself lose her balance.

"Balancing difficulties?"

Emily wanted to hide her face in embarrassment. "That's the reason my treatment was pushed back," the brunette nodded. "I tried to go out for a jog and I lost my balance." She hesitated with her next sentence as she watched her doctor look to her. "I fell into traffic."

Jennifer grimaced, noticing the nasty bruising on the woman's stump. "Did your stitches tear?"

"Amongst other things," Emily chuckled humorlessly.

Motioning for the older woman to walk over to her, the physical therapist helped her to the top of both bars. "Luckily our first day is all about your balance. It's surprising that with only one arm, your entire center of balance is thrown off." She waited for Emily to step in front of her before she continued. "When you're walking, now you're going to have to put more pressure and weight onto your right leg and foot."

The brunette started taking a few steps forward.

"Putting more weight on the side where you're missing your arm will help you find a new center of gravity," the doctor nodded to herself, watching as the older woman continued walking. "Doing this can get tiring, but it will help in the long run."

Emily frowned at the weird feeling she got as she walked the way the therapist instructed. When she reached the end of the small space, she turned back to face her.

"Now walk back to me."

The agent made her way back over to her doctor, trying to go as slow as she could to get comfortable. "Why am I doing it between the bars?"

Jennifer smiled to the older woman before turning her around and having her walk back down the small aisle the bars created. "You can practice this anywhere, but for our first time I want you between the bars so when you tire out, you have the bar to hold onto."

Hotch sat his son on his lap, pointing over to the woman he was proud to be engaged to. "How good is she doing?"

The now seven year old giggled when his father tickled his side. "So good," he grinned, watching the familiar woman massage her shoulder stump. "Go Emmy!"
