The words of assurance spoken by his Master did little to relieve the stress accumulating within Markus. His mind was in flux, preoccupied with a myriad of thoughts, though nearly all of them boiled down to the singular question: "Will I be able to handle all those people until Master arrives?"
Markus's greatest fear was disappointing his Master. While his Master vehemently asserted that he could do no wrong, that simple statement actually amplified the burden bearing down on his gut. It was the burden of expectation. Markus feared that he wouldn't live up to his Master's perception of him. Markus didn't believe himself to be as capable and authoritative as his Master believed him to be. He didn't think he was competent enough to teach those barely a few years younger than him properly. What if he taught incorrectly and ruined their basics?
