Cedric and Harry landed in a grave yard. Both were so shocked that the Cup was a Portkey that they were speechless. Now even seconds after they arrived a voice screamed, "Avada Kedavra!" and Cedric was killed instantly.
Harry shocked from what just happened didn't notice anything was going on till he was being tied up by a man in a cloak and being dragged to a tombstone that had the name TOM RIDDLE on it. When he was finally able to figure things out, he noticed it was Wormtail and got pissed off. Then he saw the thing that looked like a human child, and realized it was Voldemort. Wormtail then began the ceremony to resurrect Voldemort. He used the bone of his father, cut off his own hand, and then cut Harry to use some of Harry's blood. Unfortunately for Harry, Voldemort did not drown and was resurrected.
Voldemort then called his Death Eaters and gave Wormtail a new hand. When the Death Eaters arrived he criticized them and was anger with them for deserting him because they believe he was dead. Wormtail then untied Harry and the Death Eaters surrounded them to watch the end of Harry; at least they thought they would.
Voldemort attacked Harry first using the Cruciatus Curse and inflicting Harry with pain. As soon as he had his wand Harry hid behind a tombstone for protection. Voldemort, after they began the duel properly, attacked Harry again with the Cruciatus Curse. When Harry wouldn't answer, Voldemort screamed Imperio! to make him talk. Harry then played a little Hide-And-Seek with Voldemort until they both screamed spells at the same time. Harry, Expelliarmus, and Voldemort, Avada Kedavra. Since their wands were made with the same phoenix feather their wands connected. All of the sudden the last five people Voldemort killed emerged from the middle, starting with the most recent. Cedric asked him to take his body back, the old man told him to keep fighting, Bertha told him not to let go, his father and mother told him that they would linger when the connection broke which would give him enough time to run and get back to the Portkey. Five seconds after they had all come out Harry broke the connection and ran to the Portkey and made sure he had Cedric's body and he returned to Hogwarts.
When he returned he was so confused he barely knew what was going on and barely noticed where Moody was taking him. Moody ended up taking him to his office and talking to him trying to get out as much information as possible. Then he told Harry how it was him who put his name in the Goblet, it was him that told Hagrid to show him the dragons, it was him who helped Cedric, who in return helped him, he gave Dobby the idea of the gillyweed, it was him who set up the Portkey. He was the son of Barty Crouch and never really died. He had helped Voldemort return and he was going to kill Harry right then and there. All of the sudden the door burst open and Moody was stunned by Dumbledore. They found the real Moody in the bottom of the trunk and had Barty Jr. put under a truth spell. In the end dementors took his soul and his confession was lost. Later that day Dumbledore called Harry and Beth down to his office to talk.
