"Why is it so amusing to you?" He queried, at a loss for the first time in a long time. Uncharacteristic in one so immodest.
"Because Sherlock—" She threw her hands in the air, as was her habit. "I think you're a lovely person, I just don't believe that you could seduce me." It sounded ridiculous, even to her own ears.
"You don't find me attractive?" He asked again, eyes wide and staring, openly attempting to reveal nothing of import. That was the danger when one began to teach a pupil, they began to use your tricks against you.
She had used lovely.
"Well, no—it's not that. I just don't find you to be a suitable possible mate." She kept eye contact, wise woman.
She had agreed that she found him attractive.
"A bet." He interrupted quickly. "One month and I'll have seduced you quite thoroughly and with your knowledge of my attempts. Willingly."
"Excuse me?"
"You heard me." He smirked, without smiling, his words conveying what his face refused.
She smiled, her irritating half-smile that knew she was being played and yet dared to return his volley. "What If I seduce you first?" She asked, daring him to pause.
Your move.
