[His hands pull back when she pulls away, and he can't help but flap them around at his side in frustration as she talks, maybe kicking his desk a little. He knows what she's like. But she doesn't get that he's worried about what length's she's going to take to push this.]

And if you push it too far, you lose everything that makes us human. The human body is an amazing machine, Kit! It evolved eyes. It did that all on it's own! Don't you think that's freaking fantastic? It evolved an organ that does detoxification, protein synthesis, and produces biochemicals for digestion as well as about five-hundred other jobs all at once! And don't even get me started on the brain.

[he draws in a breath, the biologist in him trying to make up for the general frustration at her being her. He's had this conversation with her a thousand times. He knows he won't change it.]

Sure, it's a bit fragile, and a bit squishy and gross, but it got us this far. If you take everything away, what's gonna be left of you? Data? Megabytes and code that can be hacked, and altered with just a few keystrokes? I'm not saying you're not smart, Kit, because damn, you're scary smart, but. There's always somebody smarter. And if they get past your defences, how will you stop them? How will you still be you?

[he heaves a big sigh, taking his glasses off and rubbing the bridge of his nose. She knows he's for cybernetic prosthetics. She knows the job he's just taken is in a robotics and cybernetics company. But everything is different when it's about her. When she apologises, he glances at her with a frown and rolls his eyes, shrugging his shoulders.]

--Look. Just. Next time, keep calling me, okay? At least then I'll know you won't be getting mutilated by some hackjob pretending to be scientist.
