After this trailer I'm way more interested in this show than I was before. I especially love the ending where it appears Loki is actually D.B. Cooper, which tells you a lot about the weird history shenanigans he gets up to.
I'm pretty sure the main character, that we're calling Loki is the 'Variant'. The real Loki died by Thanos, then this one picked up the Tesseract, & technically shouldn't exist. He's screwed up the timeline, creating all the branches we see & has to right them.
