Jeff went upstairs to go save Juno, but he was still thinking about what Twilight told him

Twilight: tu want a horn? Well, you'll get another one, only if tu defeat me. That won't happen, but if tu somehow defeat me, you'll end up having to go against Robotnik.
Jeff: *Remembering what Twilight said* I still don't have my horn. She was lying to me. I guess I'll never be a unicorn ever again. *Continues going upstairs*
Robotnik: *Waiting por Juno* Your friend Jeffery is no match against me. He will end up dead.
Juno: No he won't. He'll defeat you, and save me.
Jeff: *Arrives* Juno, I'm here to.. *Sees Robotnik* Hello Doctor.
Robotnik: Ah, so your Twilight's Student. o at least I should say, former student, due to the fact that tu just killed her, and that tu no longer have your horn.
Jeff: Surrender while tu can Robotnik. Don't make me kill you.
Robotnik: Oh, tu have no idea how funny that is. tu won't be able to kill me, because I will call for reinforcements, and prevent tu from saving Juno.
Juno: Jeff, tu have to save me!
Jeff: I will, just hang in there.
Robotnik: *Holding up fists* Put them up.
Jeff: *Pointing revolver at Robotnik* Are tu sure tu don't want to surrender?
Nazis: *Arrive, and shoot's Jeff's gun out of his hoof, and through a window.
Jeff: I gotta admit, your army has soldiers with good aim, but-
Nazi 76: Silence. Throw your other weapon onto the floor.
Jeff: *Holding Thompson* This thing? Sure guys, whatever tu say. *Shoots both Nazis*
Robotnik: tu plan ahead. I like that about you. Why don't we forget about Twilight? tu can take her place, and we'll both rule Equestria?
Jeff: Why should I believe you? After tu told Twilight to kill me, I won't trust you.
Robotnik: Well, that's a shame. *Holding two chaos emeralds*
Jeff: What are those?
Robotnik: Some beauties that give me extra power. *Shoots lazer beam from his hand*
Jeff: *Avoids beam, then shoots bullets at Robotnik*
Robotnik: *Teleports behind Jeff, then makes gun disappear*
Juno: *Uses spell to give Jeff a horn*
Jeff: *Notices horn* Thanks Juno.
Robotnik: Ah! How was that possible?!
Juno: Changelings can give spells to anything like ordinary unicornios tu know.
Robotnik: *About to shoot Juno with lazer beam*
Jeff: *Uses spell to make Robotnik fly into a wall*
Robotnik: *Stands up* tu won't get away with this!
Jeff: *Uses magic to bring Robotnik towards him, then kicks him*
Robotnik: Ow! *Falls on floor*
Jeff: Stay there. *Goes to jail cell, and frees Juno*
Juno: *Gets out of cell* Thank you.
Jeff: You're welcome. Now get to Proxy while I finish the job.
Juno: What do tu mean?
Robotnik: *About to stand up*
Jeff: *Kicks Robotnik back onto the ground* This doctor from another world has brought misery, and violence to our world, and he deserves to die!
Juno: Maybe, but don't get too carried away with this.
Jeff: I'll do what I want when I kill him.
Nazis: *Arrive* Halt!
Jeff: *Kills Nazis with magic*
Robotnik: *Stands up* Deal with this! *Shoots beam at Jeff*
Jeff: *Shoots another beam at Robotnik*

Both beams were between Jeff, and Robotnik. It was getting close to Jeff.

Jeff: Juno, get to your plane. Proxy is already there waiting for you. Get out of here now!
Juno: *Goes away*
Jeff: AAAAAAAHHHHHHHHHHHHHHHHH!!! *Pushes beam towards Robotnik*

Suddenly, an explosion occurred. Jeff was dead, but somehow Robotnik survived.

Twilight: *Arrives* Man, what da H-E double hockey sticks happened here?
Robotnik: A failed attempt of murdering me Princess. Your student is now dead.
Twilight: Too bad I didn't get to kill him.
Robotnik: No one must find out about this. Jeff was on our side, but he killed himself with a huge explosion while trying to make a secret weapon for us. That's what we tell everyone.
Twilight: tu got it doctor.

But of course, everyone didn't believe the story, so Twilight used magic to hypnotise them, and make them believe it was true.

I, Sean the hedgehog found out about the truth when Juno was transferred to be one of the guards at a P.O.W camp I was being held in in Germaneigh. She told me after I got out of the cooler. I got in there for trying to escape, and stealing an enemy motorcycle. The changeling told me everything about Jeff, and what happened to him. We worked together to write this story.

The End.
