That clip looks like Peter and Harry fight on Harry's balcony,then in Harry's/Norman's den,then Peter picks up Harry and throws him into the Goblin's lair where Harry uses a sword to fight Peter in there.
I'm glad that scene is gonna be a big fight.
In the Goblin's lair you do see the original Goblin suit,and above the suit on a shelf is the Goblin mask with it's yellow eyes glowing,and on a table on the other side of the room you can see the Goblin's trident.
Does anyone think that Harry doesn't use that Goblin suit because Harry thinks Norman is in it talking to him.
