Odin always sits regally, this was a very Loki-esque pose. Also, at the end, when Odin is discussing Midgard and Jane with Thor, he's sitting on the throne very nonchalantly. If you notice when the guard goes to collect Loki's remains, it's the same guard Loki turned into earlier in the film. He's obsessed with the things, only to pawn one off on Loki?ģ. But maybe he expected Loki to bring it back to him with the Tesseract, kind of a gambit to risk one in order to ultimately have two. My one gripe about this connection is that means Thanos willingly gave away an Infinity Gem, which is ridiculous. This is also verified by the Collector, as he says that Asgard only has the Space Gem now that he has the Power Gem.
Most likely it is in the SHIELD research facilities that also hold the Chitauri artifacts and the Destroyer remains. The last time you saw it, it was in Black Widow's possession. He used it to control people, and it makes perfect sense as how it was able to breach the Space Gem's force field at the end of the movie, as it was of equal power. Finally, it's probable Loki's pokey stick in Avengers had the Mind Gem in it. The Power Gem is also said to grant omnipotence even without the other 5, and that was a pretty good description of what was happening to Malekith at the end (at least a better description than any of the other 5). The Aether is most likely the Power Gem, as it was shown as bright red, and its main function was complete destruction. Now, if they do decide to go with the Time/Soul/Mind/Space/Power/Reality references, it would be obvious that the Tesseract was the Space Gem, as its main function was to allow instantaneous travel anywhere in the universe. So there's our first clue into the workings of GotG. But it's clear he's collecting all 6, and he did not mention it to Sif.
If he were collecting them to keep them from Thanos, he would have asked for the Tesseract as well. There aren't too many other reasons he'd say it like this. When Sif leaves, The Collector, in a very sinister way, says, "One down, 5 to go." This could imply that he's collecting them to create the gauntlet for Thanos. This confirms the Tesseract is also one of the 6 Infinity Gems. He asks why they didn't keep in on Asgard, and Sif says it's probably not a good idea to keep two stones in one spot, saying the Tesseract is also there. This is confirmed in the post credit scene, when The Collector mentions that it is one of the Infinity Stones. While Odin is explaining to Jane about the Aether while in the library, he mentions, "They are usually stones, but this one is different." He is actually referencing the Infinity Gems, which the Aether is. Though, having a child that's half frost giant may have freaked him out, and therefore they never speak of her. He would have to have had her long before the first movie, while he is still Thor's innocent little brother. As Loki is portrayed as much younger in the movies, I don't know if they'd go this route. In the comics, it would be most likely that he survived Kurse by bargaining with his daughter to release him. Loki's daughter, Hela, is the guardian of Hel. So it's absolutely a little tidbit just for the comic book fans. Most people wouldn't pick up on this little tidbit, but Marvel is pretty specific about the dialogue Asgardians use, and they would have absolutely known Loki would never reference the Lucifer Hell. It's not a horrific place like Hades, it's simply where all Asgardians go when they die, a neutral afterlife. which is the name of the Asgardian afterlife. In reality, he's saying, "I'll see you in Hel!". When Loki is about to kill Kurse with the grenade, he says, "I'll see you in Hell!" Now obviously, Asgardians aren't Christians, so they wouldn't even understand the reference to hell.
It would be fun to read this now and remember these when you see the movie, but keep in mind I will be spoiling most everything, as there are tons of easter eggs throughout the movie.ġ.
I'll start by saying that I will be referencing scenes in the movie that won't make much sense if you haven't seen it.
