Loki Has The Tesseract
There was an interesting rumour prior to Thor: Ragnarok‘s release that stated Odin would be revealed to be hiding the last Infinity Stone left unaccounted for – the Soul Stone – inside his eye socket behind his eyepatch. This grisly fan theory turned out to be nothing in the film itself, but Ragnarok does bring a previously-seen Infinity Stone back into play.
When following Thor’s orders to put Sutur’s crown into the eternal flame and bring about Ragnarok, Loki comes across the Tesseract – which viewers of The Avengers will remember was taken back to Asgard for safe keeping after the God of Mischief attempted to steal it for Thanos. We don’t see Loki pinch the cosmic cube, but the look of greed in his eyes as he spots it is telling enough.
Tying into what we said earlier, the big question now is: is Loki still working for Thanos, or did he take the Infinity Stone for his own purposes? Is he planning to use it to oust his brother from the seat of power again? All we know is that it’s back in circulation, which can only mean bad things for the universe…
On the Soul Stone front, though, Ragnarok offered no clues to where that is. It’s possible that we’ll get a hint to it in Black Panther though, the last MCU movie before Avengers: Infinity War finally arrives.
