She says nothing to that, not willing to push it further just now. She watches him work, her attention mostly fixed on the trajectory of his fingers over her arm's mechanisms, piecing together his solution as he presents it with action rather than explanation. Occasionally she glances up at him, not entirely aware of the faint smile playing about her lips.

"Oh fuck you," she says excitedly when she ascertains the nature of his solution, her eyes widening. It's so fucking obvious. Ana would never let her hear the end of it. "Cocksucker. I can't believe you figured it out. Not an engineer. Psh."

She can't stop grinning.

He did it. It's going to take some time to finish the process but she can see where he's going and she knows, she knows he did it. The fucker actually figured it out.

The arm part, that is. That's the endgame for tonight and that's good enough.

"Fucker," she says for good measure.
