Of course, there's the risk of Stumbledore seeing that Harry will refuse to willingly ride to the rescue of the Wizarding world and "reluctantly" decide that a mind-controlled or enthralled, or even marked Harry (A phoenix * lightning bolt tattoo on his right arm, perhaps?) would be needed for the "greater good". After all, /"sacrifices must be made"/.
I seem to recall one or two fics that went down that path...
