Still eying him suspiciously, Dark Helmet thinks for a moment but then shrugs. Moving closer to him Doctor Helmet speaks in a conversational tone.
"Well, The Schwartz surrounds and penetrates all living things but by itself it neither wants or needs anything. Making it perfect to be used by anyone who can control it. It is controlled by rings that are given to those that study the way of the Schwartz. I studied under Yogurt but he got the upside of the Schwartz and I got the downside. There are two sides to every Schwartz you see."
Dark Helmet holds up his ring for the Doctor to see and points at a passing waitress carrying a tray. A glass of something on the tray quivers for a moment and then floats obediently to his hand.
"Simple really." Dark Helmet smirks before taking a swallow of the drink he just levitated only to gasp and cough a moment later with wisps of smoke drifting out from the edge of his open helmet.
"What was that drink?" He manages to gasp as he tries to fan his tongue.
