Let me preface this by saying my course of hypothetical action with the wand is pretty fucked up and these few paragraphs may be triggering for some.
I would magically snap myself back to a morning in March of 2015. Then I would proceed to relive one of the true horrors of my life in order to see how receiving it differently would alter the outcome. I would transport myself back to the exact moment that a young man (whom I invited over to my apartment for coffee and bong rips before our college classes) began raping me.
I know it's a sadistic choice for me to force myself to relive rape, knowing that I could put myself farther back in time to prevent it from even happening... but the fact of the matter is, my present self, being offered the magic wand, has already lived it and wants justice.
After finding myself in that precise moment, with no conscious knowledge of the future or the magic at play, instead of freezing up and taking the abuse, I would fight. I would incite physical violence, making sure I scratched him, getting his dna crammed under my fingernails. My intent would be to fight hard, but not hard enough to win, only enough to receive a few blows before he got his fill and carelessly left.
My blood and bruises would then serve as my proof, pure evidence of his intent. I would of course then document all of this correctly and report it through the proper channels. I would go to the hospital and get a rape kit done, stitches if I needed them, and then I would press charges. I would fight in court, and hopefully send that motherfucker to jail. At the very least I would easily have him expelled from my university.
Most importantly of all though, I would approach the love of my life with my bashed up face and bruised limbs, telling him the pure truth and he would believe me.
