 Why did Simon's new friend not give him an aspirin when Simon asked for one?
He sat down at his desk, passed his tongue over his teeth in distaste, groaned, fumbled in a drawer for the aspirin bottle. "Providence," Simon told her whilst fiddling with the aspirin bottle, "will provide." Something where you could deduce that actually the ruby ring had gone down the drain and was caught in the elbow.

He needed to knock him out to go back to the festival so that Simon would not know what had happened.  He gave him a different medicine instead that he thought would work better.
