Q shakes his head briefly. "You'd vary the ingredients to suit the individual of course, depending on what was wrong with them. But that still would affect the colour of the finished potion," he goes on to himself. "A ground state?" He frowns. "You'd most likely start with a standard list of ingredients and go on from there. Something else to look into." He notices Severus' wince and his grin widens. "Those are nice too. I wonder if you can still get lava lamps?"
"Oh," Q shrugs and dismisses the matter. He stares at Severus. "Sirius Black is an Animagus?!" He blinks. "I suppose I shouldn't be surprised. What's his animal form; a wombat?" He snickers.
Got it! Thanks! I'll try to get it to you sometime this weekend, barring sunspots.</i>
