    "Together, 1, 2, 3..." Cedric and Harry took hold of the Triwizard Cup....

    And things start to go a little differently from there.

    Just the smallest amount of interference reeks havoc with the entire Second Wizarding War, and - of course - Harry's life, because when did that ever run true to course? He's not sure he should complain though, given that the Dursleys have yet to make an appearance.

    Summary

    not beta-read, and uh, updates are gonna be real slow :)
    Harry felt dizzy. The world was spinning. What had happened? There was a dirty shade of gray and green mingled. Oh, grass? And that's a...crumpled house? He racked his brain. He couldn't remember what happened-thump. After puking a bit, Harry felt, and could see, considerably better.
    Wait. Harry now wished that he was sick again, the thump was Tom Fucking Marvolo Riddle falling on the ground from nowhere?

    Summary

    “The Ministry takes a vested interest in ensuring our young witches and wizards are as safe as we can make them and you, dear boy, are very important to Minister Fudge.” Professor Umbridge said, simpering in a self-satisfied way as she said Fudge’s name. “So I must ask you where you’ve been this last August?”

    Harry coughed into his tea and nearly spilled it over himself.
