Not that he's stuck up, but he's a man of many skills, and they seem wasted on coffee boy. "Well, that's really good of you. And it's good I don't have to shoo you away from the important stuff. Not that I've really been hands on with it myself. Mostly I've been sticking to my equations." An engineer, she is not. It's times like these she wishes MacReady were here. Now there was an engineering genius.

Her eyes find the equation she was working on and she sighs, taking a moment to sip her coffee. "Maybe I should get a second opinion on this, to make sure I'm on the right track."
