[ WP ] You are a minor character/nameless minion in a fictional story , during a battle between good vs bad , you accidentally killed the protagonist/antagonist . What happens next ?

He was going to go out there, and he was going to die. I could see it in his eyes. And that was something I could n't let happen. He was our last hope. If he was dead, then our future would be as grim as this last year. 
 
 I've learned much from all of our classmates. A few discarded branches and a few sticking charms, and suddenly, I looked like an innocent bush. Several notice-me-not spells on myself completed the ensemble. Together, it made it appear to anyone that looked that I was just a uninteresting plant. Ironic, considering my specially. 
 
 Harry said to kill Nagini, but his life was more important than Voldemort's snake. That could be taken care of later. Besides, it was probably next to the Dark Lord anyways. Two birds, one stone. That's what they say, right. 
 
 There was a quick detour to the greenhouses to fill my pack with the needed items. Apparently my notice-me-not disguise was good against magical plants. Good to know. 
 
 Then I ran. I ran as fast as I could into the forest, casting whispered point-me spells to track down Harry. 
 
 There I saw him, facing off against the dark lord with quiet acceptance. I took a deep breath. I was scared, terrified, but it had to be now or never. 
 
 I put on my magical ear-muffs, just in case and readied my wand. To everyone else standing in the clearing, the world's most uninteresting bush scuttled across the open space to stand at Lord Voldemort's back. A small branch-looking wand extended out from amongst the leaves. 
 
 I did n't know what I planned to cast. Perhaps a piercing curse at Voldemort's black heart? Then, it did n't matter. 
 
 Because that was when the stitching on my bag gave out, spilling fully mature mandrakes all across the ground. 
 
 Twenty-one fully mature mandrakes - seven times three, fell onto the cold uncomfortable earth. All of them took a deep breath in perfect synchronization. 
 
 There was only time for one quick spell and so I cast it with all my power. A *silencio* targeted at Harry Potter's head. 
 
 Then the screaming started. 
 
 The time spell said that I was only unconscious for half a minute. The sound of the mandrakes had faded until my magical muffs were able to block the remainder of the sound. I quickly repaired my soundproof bag and stuffed all the fallen screaming roots inside. 
 
 I checked the area. All the Death Eaters - dead. Nagini, who was at Voldemort's side - dead. Most everyone else in Voldemort's camp - dead. Hagrid - unconscious and snoring. Voldemort - quite dead. A strange disappearing black smoke coming out of Harry Potter's scar - dispersing quickly with a pitiful wail. 
 
 Harry Potter - alive but unconscious. 
 
 I used most of my magic casting the overpowered silencing charm, but I still have enough to levitate Harry back to the castle. 
 
 Weeks later, I was approached by Hermione Granger. Harry had awoken a few days prior and she expressed her gratitude to me for saving him. Frankly, I've had enough gratitude from everyone by then. 
 
 The moderates were celebrating the fall of Voldemort. The conservatives were celebrating that it was a pure blood wizard and not Harry Potter, the boy-who-lived-to-be-a-decoy, who had killed him. Draco seemed lost now as an orphan. So many had died or lost family during the battle of Hogwarts. 
 
 But it was Hermione who had filled me in on a fact that she considered amusing. There was a prophesy that said Voldemort could only be vanquished by one of two boys - myself or Harry Potter. And that it could only be done with a'power he knew not'. 
 
 Apparently, Hermione did what she did best at - research, and found out interestingly enough that Tom Riddle had never taken Herbology during his time at Hogwarts. The class was an elective during that time. 
 
 That meant one thing. Voldemort had no consummate idea of what mandrakes were.
