It is stated that "Rennervate is the counter-curse to the Stunning Spell. It is used to bring stunned individuals back to consciousness." It's not stated anywhere that Rennervate brings only stunned individuals back to consciousness: it is implied that rennervate brings unconscious people back to consciousness, making Rennervate a medical spell, rather than a counter-curse, which changes the charm effects. (Once a person is hit by Stupefy, he or she doesn't bear any charm effect, thus rennervate cannot be a counter-curse.) --EXE.eseguibile 10:41, August 5, 2010 (UTC)
