After a tour of the winter fortress, the couple found themselves alone in the library. While Zi's eyes roamed the many columns of books, Robb watched her with curiosity. Her movements in the library were silent and graceful. Did her feet even touch the ground?
She seemed lost in thought, and he didn't want to ruin her concentration.
You're not. She met his eyes as she smirked at him. Robb smiled in return.
"Who is Cersei Lannister?" She questioned aloud with intrigue. His blood turned cold at the mention of House Lannister. House Lannister was not known for their honor or courage, only for buying others. Zipporah could feel his disdain for House Lannister but did not regret her question. She needed to learn who was who in this strange world. With every passing moment, she knew that she would not be returning to her home.
"She is the Queen of Westeros, married to King Robert Baratheon." His voice was a bit strained. Zi continued to walk around the large library, "Gwen said I'd make her jealous. Why?" Her sky blues met his blue greys. They held each other's gaze for what felt like an eternity to both teens.
Finding his voice, Robb murmured, "She is said to be the most beautiful woman in Westeros, but I believe she has been dethroned." Zi fought a blush but utterly failed against it. Robb noted her rosy cheeks in response to his compliment. Nothing he had said was a lie. Cersei had been replaced by the goddess before him. He acknowledged that she had strange ears, but to him, they only increased her beauty---making her more exotic.

"Tell me Lord Robb, what is there to do in Winterfell? Besides reading, sewing, and eating?" Her voice was light and entrancing. Shaking the cobwebs from his mind, he teased, "Are you looking for adventure Lady Zipporah?"
"Only if you'll be my partner in crime." Her eyes widened at her own words. What the force? That was supposed to be an inner thought!
He grinned at her reaction to her own words. Closing the distance between them, Robb couldn't help but be close to her. He was drawn to her. They barely knew each other, but the closer they were, the better he felt. Robb knew it was selfish of him to act this way, but something in him had to be with her. Ever since he had lightly touched her soft fingers with his, he had a hunger in him.
Zipporah was unsure of how to respond to his movement. They were inches apart, and she could feel the warmth emanating from him. "What is this?" A smug voice teased from the doorway. The duo took several steps away from each other and turned to face Theon.

"Robb, it's training time. Milady, Lord Stark extends an invitation to watch the sparring."
"We'll be right there, Theon." Robb answered as he moved to obstruct the Kraken's view of the girl. Turning to leave, Theon made a hand gesture causing Robb to stiffen. Sensing his anger, Zi placed a hand on his shoulder. Immediately, the force followed between them. Neither had ever experienced anything like it. In a swift movement, Robb pushed the duo into an aisle that was rather dark and away from the door's view. Attempting to figure out what he was trying to do, Zi whispered, "what's going-" before she could finish, his lips were on hers. Soft, warm, passionate, urgent---different thoughts flittered through her head. She had just met him a few hours earlier and now she was in his arms. There was no place she'd rather be. The connection that flowed between them was unreal. The longer they remained touching, the more they'd be connected. Her mind reeled at every movement. This was a bond. They were bound to one another.
He pulled away to look at her. Feeling flushed and breathless, Zi blinked a few times. "Milady, I apologize for my behavior. I do not know what came over me-" Her hand covered his mouth and murmured, "Never apologize for that. We are connected. It cannot be helped. I am yours." His steel blues widened at her words.

Mine.

Yes, yours.

Gently removing her hand, his lips were on hers again, more aggressively than before. Zipporah felt his signature then---a large grey wolf with a bluish turquoise aura.

My wolf.

She wasn't surprised when a rumble sounded from his chest. Stifling a moan, Zi nipped at his bottom lip. He jerked away in surprise. Both of their lips were swollen and red.

"We should go before he comes back. I sense his desire to spy."

Robb silently nodded as he grasped her hand. The couple walked quietly to the yard.

You're going to watch, right?

Of course, I would like to see you beat the shit out of the kraken.

You've got a mouth on you.

You'd know.

The duo's mental conversation was interrupted by Theon shouting at Robb to hurry his arse up.
Letting go of his hand, she watched him stalk toward the practice yard. She then moved to the viewing area where Lord and Lady Stark stood. Lord Stark noticed the girl's bright eyes on his son. Even as she regarded them with a bow, her eyes were on him. Lady Stark seemed to notice it as well. "Winterfell is lovely. Robb showed me all the different rooms."
"Thank you. Did you find anything interesting?" Lord Stark questioned in a hushed tone. He did not wish to interfere with boys' training in the yard.
"The library. I liked the library." Her eyes danced at her memory of their connection. How were they supposed to deal with this bond? She had never heard of anything like it before. Then again, the force works in mysterious ways.
"Theon and Robb. Suit up." The Master-at-Arms ordered. The two dressed in combat attire and held practice swords. Zi noted that Robb looked more at ease with the weapon than Theon. The two circled each other, and then Theon slashed at Robb who easily dodged the strike and delivered one of his own. Theon was surprised at Robb's display of strength. The two clashed swords again and seemed to be in a deadlock. Zi's hawk-like eyes caught sight of Theon leaving his left side open every other encounter.

Next encounter, Theon leaves his left side open.

She smirked as Robb cocked his head in reply. A smirk graced his lips as Theon struck again only to find that Robb had twisted out of it and delivered a deadly blow to his left side.
"Winner: Robb. Excellent work my young Lord. We will begin practicing live steel moves in a few moments."

Zi greeted the two at the exit of the training yard. "Like what you see?" Theon crowed as he spotted the beautiful girl approaching them.
"Of course, I thoroughly enjoyed watching Robb beat you." She smiled sweetly at him as she passed by him to speak with Robb.

I am sorry for helping. I shouldn't have intruded in the fight.
I'm glad you did. You saw something I didn't.

The Starks watched the two smile at each other. There was something between the two. Lord Stark was thrilled at the idea of the two being together. Lady Stark, on the other hand, did not trust the girl yet, and the idea of her wooing her eldest did not sit well with her.

I was fighting for you.

My wolf.

Robb momentarily forgot himself and touched her braid his his hand. Theon watched from beside Jon who seemed amused. "Is it me or are they being a bit forward?"
"That's rich coming from you." Jon muttered as he moved away from Theon and toward the couple.
"Robb, how did you spot the weak side?" Jon questioned as he approached them. Robb let his hand drop from her braid and smiled, "It just came to me." He added a shrug at the end. The strange girl kept her face neutral at the exchange.
"Lucky thought." Jon commented as he regarded the female who had his brother under a spell. Getting a better look at her, Jon easily understood the girl's pull on his brother.
"Milady, I am Jon Snow. It is a pleasure to meet you."
"Jon, it is nice to meet you." Her voice was strong and smooth.

Who is he Robb?
My half brother.
Why did I not meet him earlier? I'm confused.
My mother doesn't treat my father's bastard as an equal.

Zipporah wasn't sure about this custom. Jon seemed nice enough. Why blame the child for his father's mistake? Her eyes watched the two brothers talk enthusiastically about practicing with live steel.
"Rodrick Cassel, this is Lady Zipporah." Robb's voice interrupted her musing about family. Sir Cassel bowed to the blue eyed beauty before him. She curtsied in reply. He noted that her gait was that of a fighter. "Miss, forgive me for being bold, but where you're from, you were trained in combat, were you not?"
Throwing her head back in laughter, Zi nodded enthusiastically. "I believe this is the boys' session. I'll join another time. I would hate to ruin Sansa's dress, and besides, I don't think Theon's pride could handle losing to a girl."
He'd never touch you. Mine.
