Well, what had she expected? Happiness and trust? Nah. And Yura wasn't displeased by the negative reaction. In fact, she smiled a bit at his response. It was childish, but still good. He tried to expel a genjutsu first, very smart.

Her eyes whirled, memorizing everything about this moment. Though her main reason for turning her eyes on was simply so he'd know, without a doubt, who and what she was. An Uchiha like him. And now he believed it. But he didn't know what side she was on. She didn't blame him for that wariness. 

She tried not to smile wider at his following threat. She copied the handsign, eyes twinkling now with amusement.

"Oh yeah?" she raised an eyebrow. "Me too, kid." Then she quickly dropped her hands back into an unthreatening pose. 

She slowly crouched to get even with his eyes, hoping he wouldn't startle and attack. "Very wise," she said approvingly, warmly. "But unnecessary." She didn't say his weak defense was useless against her or anything condescending and cocky like that. She said it simply was not necessary. 

Her face gentled and she slowly held out her hand for a handshake. She was wearing fingerless gloves, covering her palm,  but there were tattoo-like lines down the underside of all her fingers ending in a dot on her fingertips. It looked a little weird, perhaps threatening. It wasn't meant to be though and it didn't even occur to her to that they might be. 

"We're the last Konohagakure Uchiha, Sasuke-kun. I'll train you, but I won't fight you."
