Reasons why Frostiron:
You will note that, of the entire cast of The Avengers, Loki is the only one who gets two nicknames: Rock of Ages and Reindeer Games. The latter of these two is bestowed literally five seconds after Tony’s initial meeting of Loki—and Tony knows Loki’s the villain. He knows that, and yet he’s still doing his whole “let me give you a nickname so maybe you can feel more comfortable around me and I can let you know that whatever differences you have, I don’t care, you’re just a person in my eyes, and yeah everyone eventually leaves and/or hates me, but maybe you won’t; it’s worth a try anyway” spiel.
You will note also (and maybe I’ve pointed this out before but it’s probably my favorite thing about this pairing) that of everyone in the whole movie, Loki chose Tony to go after with his spear. He could have chosen ANYONE ELSE:
- Thor, who we all know is so desperate for his brother to love him again that, had Loki lied and said ‘I’m ready to come home’, Thor would have opened his arms, providing the perfect opportunity for Loki to tap him with the spear
- Clint, who had already been under his control for most of the movie and who had done a pretty damn good job with the time he had
- Natasha, who was “one of the few people who could actually sneak up on him” and who, as Loki probably figured out, would have been perfect to help kill members of SHIELD without the use of magic
- Bruce, whose powers are enough so that if Loki had controlled him, he could’ve demolished the entire country within minutes, giving Loki the opportunity to quietly take over and rule in the time of widespread panic and vulnerability
- or Steve, who was a soldier and who was used to taking orders, and who could have used his serum-induced capabilities to wreak havoc
But instead, Loki chose Tony, and why? Because:
- he saw how brilliant Tony is, and how he could’ve used that brilliance to build something more powerful than he had to demolish the city, take over Midgard—and eventually Asgard, when it came down to that
- he saw that Tony is an outcast among the Avengers, and that the only thing keeping him on the side of the angels is Yinsen’s death (although Loki doesn’t know about that, he would’ve learned when he tapped into Tony’s mind)
- he saw that he and Loki are alike, that they think alike and look at people the same way and have the same quick wit and basic mentality (and he would have eventually found out about their pasts being so similar)
- and plus all that, Tony is hands-down the best-looking Avenger, and why wouldn’t Loki have wanted him on his side and in his bed and all that?
So yeah, Frostiron makes sense. A lot of sense.
SORRY I OVER-ANALYZE THIS MOVIE WAY TOO MUCH.
