20 Unanswered Questions From 2017's Comic Book Movies
9. Did Loki Steal The Tesseract? - Thor: Ragnarok
The Question: When Loki (Tom Hiddleston) is seen mooching around in Odin's (Anthony Hopkins) vault, it's implied that he may have stolen the Tesseract. Is this the case, or have fans been expertly trolled?
The Likely Answer: Infinity War's first trailer seems to suggest pretty blatantly that Loki did indeed steal it, considering that he's shown presenting it to someone, presumably Thanos.
It's entirely possible we're being deliberately misled and the circumstances by which Loki gains possession of the Tesseract are far more benevolent than they seem here, but considering Loki's stature as the God of Mischief, it's far more likely he's up to his old tricks once again.
Thanos is sure to have a far less welcoming response to him this time either way, though.
