I appreciate that, but he can probably work it out. [More like potentially read this man's mind, but Martin isn't going to immediately spook him. He's paranoid enough as it is.]

He was the head of the Institute I worked at back home. I quit before I came here, though, so... not my boss anymore. [He shrugs a shoulder and finally picks up one of the biscuits from the tin he'd brought down.] Was he being weird and creepy at you? If yes, that's just the way he is. It's nothing personal.
