A/N: Two left. NOOOO! I won't keep rambling; I'll just let you read it. :D Enjoy. X By the way, (mainly just to remind myself) Yin is represented by the black side and Yang is represented by the white side. :)

Y is for Yin and Yang

"I'm sorry for the interruption, Mrs Wan." said Lisbon apologetically. She smiled feebly at the Asian woman. "Thank you for your co-operation."

"Oh, it's no problem, Agent! Really, it's nothing. Anything to help with the case, I'm happy to do whatever you need me to do." The woman nodded. She regarded both Jane and Lisbon with gentle eyes and a smile.

Jane politely shook her hand as a gesture of appreciation and turned towards the door. They made to leave but were stopped by Mrs Wan's voice.

"Hang on, you two." They looked at her. "Now, I apologise for any intrusion here, but…" She walked over to a small desk and opened the top drawer. She pulled out two objects wrapped delicately in white cloth. "I think that you two could put these to better use than I can. They belonged to my great grandmother and they've been passed down through many generations. However, I have no children, so who am I to pass them on to now? I couldn't bear to see them in irresponsible hands." The woman walked over to them and placed one in Lisbon's hand and the other she gave to Jane. "Think of them as gifts for all the help and support you've given me in these hard times."

Lisbon looked curiously at the small package. "Umm…Thank you, Mrs Wan. We'll be in touch." The pair turned and left with one last nod. The woman watched them leave from her front porch and then closed the door, smiling to herself as she fondly recalled the memories associated with the gifts she had given. It gave her great pleasure to know that they were indeed in capable hands.

Once they were in the car, Jane and Lisbon simultaneously unwrapped their packages with care. Lisbon let out a small gasp and Jane just sat and stared.

Both of them held in their hands one half of a Yin Yang medallion that, when held together, would make up the full symbol. Lisbon admired the ancient yet well looked after trinket, holding it gently in and focusing on not dropping it. Jane traced the edges of the white pendant, remembering what the symbol meant.

"It's…beautiful." She gushed, gazing at the elegant, black sign. He nodded in agreement.

"Lisbon."

"Yeah?"

"Do you know what these symbols mean?"

"Umm…No. Not really. I know they're an important symbol to certain cultures but…"

"They represent the balance between negative and positive. They show that everything is made up of two equal parts and you can't have one without the other. For instance, you can't have just light or just darkness. Just the sun or just the moon. Everything has to be equal because too much of one is considered a bad thing."

She raised an eyebrow in fascination. "But why would she give us these? I don't get it."

"Well…" She picked up on his hesitation and watched him expectantly. "They're also thought to represent the two halves of a relationship. The female half, which is Yin," he pointed to the black pendant in her palm. "And the male half which is Yang." He held out his hand, putting it next to hers.

"A…relationship?" her voice had dropped to a whisper. They sat and admired them for a moment, chaotic thoughts darting through their minds. "Does she think we're in a relationship?"

"I don't know. Either that, or she thinks we should be in one."

Lisbon chortled next to him. "Really? Us?" He shrugged and her smile faded. "I…I—"

"I don't know what she meant by this exactly," he said, holding up his half. "But I do know one thing."

"Oh?" she whispered, her voice breaking a little. "What's that?"

He closed his eyes for a second, clinging onto the emblem.

"I definitely couldn't carry on without you." He looked up, meeting her eyes. They displayed such raw emotions that momentarily, she couldn't breathe. "I wouldn't even be hereif it weren't for you. I guess this equality stuff is true. I wouldn't have been able to do anything on my own. I'd still be the cold, broken man I was before if it weren't for you. You've changed me. For the better. You've helped me through so much these past few years and I honestly…I don't—" His voice fell to an almost incoherent whisper. "I need you, Lisbon."

Bam! Just like that, her heart skipped and the tears pooled in her eyes. She sniffed, trying and failing to hold them back. Jane flashed the tiniest of smiles and breathed a ragged sigh. He wasn't used to displaying his feelings to her so honestly. In fact, it took his breath away at how alien, yet how easy it felt to pour his heart out to her.

They watched each other, green eyes meeting blue and hearts matching in pace. Then, she placed her half of the pendant next to Jane's in his hand, fitting them together to complete the whole picture. She curled his fingers around it and rested her small hand over his, holding it gently.

"I need you too. I promise, I'll always be here for you, no matter what."

"Thank you, Teresa." He opened his hand and stole a glance at the completed emblem, feeling several warm tears slide down his cheeks. "Thank you so much."

A/N: Sorry if I got any of the facts wrong! I did do some brief research on it, but I take full responsibility for any factually incorrect parts. Hope you all enjoyed it! :D Last chapter next! :O
