MEGA RANT RIGHT HERE + INFINITY WAR SPOILERS!!! Seriously if you haven't seen infinity war run away. Okay so we know Heimdall probably isn't coming back, but it's Loki that I'm talking about. I found a loop hole in marvel, Loki was adopted by Odin and when he saw Odin he mimicked his appearance. Considering Hela has black hair and she said Thor doesn't look like Odin, Odin probably had black hair which is why Loki has his hair that color. Maybe frost giants just have black hair though, because when he found o he was adopted he turned blue and kept his hair normal but this was probably just so we didn't know he was blue until he turned around. When Loki dies, whatever spell he has that makes him look more human would die with him. When Loki "dies" I'm the dark world, his skin changes color which means he was actually dying or, in this case, pretending he was as his spell wore off. When Loki gets his neck snapped in Infinity War, his skin stays the same color and he doesn't turn into his natural state of blue. If Loki was really dead, his spell would wear off and he would look like a frost giant. If Loki isn't dead, he would be in space after the ship blew up, and since Thor can survive in space, so can Loki Secondly, Lokis planning makes no sense. Loki avoided Thanos once after he failed him in the first avengers, he faked his death (multiple times) and rarely gets tricked by anybody. He's the God of mischief and lies, so him trying to pull out a dagger to kill Thanos doesn't make sense. Loki is smarter that that. Another hint is when Thanos is choking Loki, he says "you will never be a god.". Loki knows Thanos never aimed to be a god, so saying this just as his last words doesn't make sense. Loki probably meant that Thanos would never be a god like him, and considering his history of trickery he might mean that Loki knew he was going to live and he was taunting Thanos. By saying you will never be a god, he was telling him that Thanos could never kill him. And lastly, this ones weak but hey, in the leaked pictures of the set in avengers 4, tom Hiddleston is in his outfit from avengers with his little muzzle gag thing, being escorted by Thor. This can either be a flashback, Thanos using the time stone to go back that far, or the reality stone being used to mesh realities. Gamora will most likely come back, seeing as they already have a release date (May 2020) for guardians of the Galaxy 3 and gamora is supposed to be the lead in that.
