Avengers: Infinity War—All the hints and clues in the marvelous new trailer

As Tony Stark goes to investigate some sort of commotion outside, we cut to Spider-Man (Tom Holland) sitting on a school bus when the hair on his arm perks up, indicating his Spidey senses are tingling. He looks back toward New York City and sees some kind of giant ring structure hovering over the city. No doubt a portal for Thanos to travel through.

Among rubble, Tony Stark takes off his sunglasses and looks toward the structure, obviously concerned by what he’s seeing. As several people have pointed out, it looks like Tony has reinstalled his arc reactor, which he removed at the end of Iron Man 3. We then see Loki, presumably handing Thanos the Tesseract (Space stone) in a big sign of allegiance.

After seeing the danger from afar, Spider-Man springs into action wearing the spiffy new armor presented to him at the end of Spider-Man: Homecoming. It’s unclear what Spider-Man is hoping to achieve, but he’s managed to make his way atop the ringed structure.

It’s tough to tell where the next shot is taking place, but it looks like it’s out in space. Thor stands in the middle of a ringed structure as he attempts to activate switches.
