What is Slake's opinion of Dennis McAlvane in the play, Y2K?

McAlvane is in the Secret Service and seems intent upon pleasing his superior, Slake. He is quick to speak in Slake's direction and quick to act at Slake's request. Without really showing a personality of his own, McAlvane is eager to display a knowledge of Slake's methods and desires. Slake calls him "Mac" and seems to look upon him as a promising protégé.
