I couldn't get this idea out of my mind so here is a story based on Rusty since there aren't that many and his half-sister who we do not know in the show so she'll be called, well you'll find out later. This is set when Rusty is twenty-eight and an aspiring lawyer in family law. So, here we go.

The female police officer nodded curtly as he stepped into the office, placing his briefcase on the desk.

"I came as soon as I could. Are you sure that no other lawyer could take this case?"

She sighed, folding her hands behind her back as she looked down. "It's a... delicate case here, Mr Beck. A child has been... abused."

Rusty nodded, folding his arms. "How old is she?"

"Seven, going eight. She seems fine but she asked for a female to be present at all times. She is wise beyond her years. Talking fluently and defiant but I don't think she understands what happened to her."

"Where was she found?"

Lieutenant Byrnes pursed her lips before replying, "Somewhere downtown. A woman came across her and called the authorities."

"Is it alright if I ask her questions now? Or should I wait until the morning? It is quite late." Rusty asked, checking his watch.

"She said she doesn't mind being interviewed right now. The sooner the better, I guess." Byrnes replied, leading him out of the office into the interview room.

When Rusty entered, he saw a young blonde girl with dark brown eyes and the saddest frown. He recognised those eyes.

He sat down across from her and offered a small, comforting smile. She gasped subtly but maintained her frown. She looked behind her and the female social worker offered a comforting smile as well, nodding so she knew that he was one of the 'good guys'.

"Hi," Rusty started. He wanted to call her 'love' or 'sweetheart' but he felt that one of those may trigger her. "I'm Rusty and what's your name?"

She looked down before looking back up. "Hope," she whispered so quietly that he could barely hear her.

"Hope? That's a hopeful name..." He attempted to lighten the mood but she looked away from him to Brynes.

"What are you? Why are you here?"

Rusty's eyes trailed down to her neck where a heart-shaped locket laid. "I'm a lawyer. Well, an attorney. I'm here to help you put the bad guys away so they don't hurt any more people."

"You're not going to hurt me?" Hope mumbled.

"No! Never." Rusty assured her, maintaining his distance and preventing himself from touching her hand which picked at a piece of bread on a plate. "Do you like burgers?"

The girl nodded, looking up at him. "Cheeseburgers are my favorite."

Rusty turned around to face Brynes. "Do you mind? You can charge me later."

She sighed, nodding before leaving the room with the door making a 'click' behind her.

"Where are your parents, Hope?"

Hope shrugged. "My dad is in jail. I think. I've never met him but that's what my momma told me before she left me."

"When did she leave, Hope?"

"Four years ago."

"Did you have anyone else looking after you, Hope?" Rusty gently pressed.

She nodded. "They didn't like me though. I ran away."

"When was this, Hope?"

Hope looked up. "You're saying my name a lot."

"It's a nice name. So, when did you run away, Hope?"

"Two years ago."

"You were five or six?" Rusty gasped. "That's a really young age to run away, Hope."

Hope shrugged, "I know. They didn't like me and I didn't like them."

"Why did you run away? Was it because of your mom?"

She nodded. "That and they didn't like me. I heard them talk about me, saying that they never should have let me stay with momma."

"So, where have you been staying for the past two years?" Rusty asked.

Hope shrugged. "I stayed with these other girls, they worked at night so they could play with me during the day. But one died and the other ran away so I live on the streets now."

"When was this?"

"Last week."

Rusty nodded, writing in his notebook. "That's a nice locket, you've got there." He said, his gaze down at what he'd written.

Hope smiled. "Want to see what's inside?"

"Why not?" Rusty replied, looking up at her.

She unclasped the locket and placed it in his waiting hand. "There's a picture of me in there."

Rusty opened it up to see two children. One of a young baby and another...

"Wh-who is this?"

"My half-brother. My momma says that he's really successful so he never has time to see us. Well..., she said that. I want to find him. I've started looking for him."

Rusty continued to look down at the locket, his heart beginning to tighten in his chest. The young boy had blonde hair and a scowl but it was very evident to him who it was.

"Did your mom ever tell you his name?"

Hope smiled even wider. "You have his name! His name is Rusty! Just like yours. This would be a... a co-in...-"

"Coincidence?" Rusty finished for her.

"Yes! That! Isn't that funny?" Hope grinned.

Rusty gave her back the locket and stood up. "I'll be right back,"

He exited the room, retrieving his phone from his pocket just as Brynes returned with a food bag.

"Mr Beck? You look like you've seen a ghost. What did she say to-"

"I need a DNA test done. Immediately," Rusty cut her of.

Brynes stood there confused. "Of Hope? Matched with who?"

Rusty gulped, his phone going to his ear as he heard his mother's voicemail.

"You've reached Sharon Beck. Sorry, I can't answer right now but I'll get back to you!"

"Me."
