That smirk quickly disappears into a frown. She looks honestly upset, but can that be taken as is from a professional liar?

"Are you saying you lied to me before, about bringing others back to your ship? Because that seems like a harsh thing to do to someone you just met. That's hardly a fair thing to tease someone about." Her brow furrows and her lips draw into a thin line.

"However, if you worry about my not knowing the technology which your world uses, I'm sure you'll find me in a much better place than when last we met. Give me a few days and the right literature and I'm certain I could get close enough. I've been... busy the last few weeks and have gotten used to many new things." She raises an eyebrow at him as she crosses her arms in front of her chest again. If he's not paying attention, though, he'll miss the wink.
