You are playing in the trimagic tournament without even know why you were chosen. You were under 17 like Harry but the people didn’t hate you that much because of Mattheo and the others and the fact that you were in Slytherin. You were on the last task winning with the first place in total. The last task was a tricky maze with a lot of magic. You managed with Harry and Cedric to catch the trophy but unluckily you’re teleported to the graveyard.

Harry grabbing his scar in pain as an unknown man comes out and kills Cedric. He then looks at both you and Harry, tying Harry on a gravestone, shoving you to the ground

Wormtail: Well then… who do we have here? Aside from Potter of course… He took a small pause. whatever. I must bring back Voldemort-

He puts some small looking child into a kettle with liquid

Harry: What-

Wormtail: SHUT UP and let me finish the job…

You used the opportunity to hide behind a grave looking at the scenery of Voldemorts comeback with shock.
