You are now Harry, several hours in the past.
You're still at home. Stuck. In the epicenter of a raging war.
As a well-known bard (NOT THAT ONE) once said, all the world's a stage. You, however, have until now elected to take a seat in the audience, rump plush-ly coddled by the familiar embrace of your living room couch. Is it time to sit back and watch the show...?
No.
It's time to get off your ass and PERFORM.
