You appreciate Xanatos making the offer honestly, you do. But you just… don't want to be beholden to him like that. It would feel too much like he was controlling you. You politely tell him no, and then usher him to the exit. You have an important meeting in a few minutes, one you have not told him about. As he leaves, you look over the counter in front of you and pick the screw back up. You look at it and then decide, for whatever reason, that it might as well not go to waste, and use it to tighten up one of the clock hands. Xanatos looks over his shoulder at you drilling it in as he goes.
He smiles.
