1. Volstagg's Warning (Thor: The Dark World Mid-Credits Scene)
"It is not wise to keep two Infinity Stones so close together." Those were the words of Volstagg of the Warriors Three as he and Sif handed over the Aether to the Collector in the mid-credits scene of 2013's Thor: The Dark World. The Aether had come into the possession of Asgard after Thor defeated the Dark Elf Malekith, who had acquired it with the intention of using it to plunge the entire universe into darkness. However, having already come into possession of the Tesseract after Loki's failure to conquer Earth in 2012's The Avengers, Asgard opted not to keep the Aether, as bringing Infinity Stones together is dangerous. This was clear foreshadowing of the Avengers: Infinity War movies, as Thanos should have all six of them in his possession in by the time they come around - and he's going to be extremely dangerous as a result. What do you think? Have there been any other moments in which the Infinity War was foreshadowed in the Marvel Cinematic Universe? Have your say below.
