Thor is confused.
It's not so much Midgard that confuses him (well, it does but he's getting used to it) but how everything has changed. Not so long ago, he had been living in Asgard with his friends and his family – the Warriors Three, the Lady Sif and his parents… and also his brother, Loki. The times hadn't been exactly peaceful, of course; Asgard had to be protected from Frost Giants and other evil creatures and up until recently, Thor had been glad to fight them for glory and honor and victory. But then he had made a mistake and everything seems to have gone down from there.
There is a game in Asgard called the Game of Thrones – it's a game consisting of several tokens and dice and it's rather lengthy and complicated. Thor has never been too fond of it for it included too much strategy and far too little action for his taste but Loki had always been a master player. While Thor had struggled to keep his gaming pieces together, Loki had won one round after another. Somehow, this had always irked Thor somehow; he had been used to always winning, always getting the spotlight, always been the better son to Odin. Until Jotunheim, that is.
After Jotunheim, everything that's happened reminds him of another lost round of the Game of Thrones – first, he'd lost his home, then his brother. Thor cannot stop these things from happening, he is yet another piece in someone else's game and he is lost and confused as to what he should do. What he can do because he might be considered a god but he's certainly not almighty.
The Avengers – he likes that name, it reminds him of past battles and lost glory – are gathered in the kitchen for breakfast and Thor stares down into his bowl of milk and colored wheat rings (Clint has explained that they are called cereals) while the others share their usual morning banter.
"Gentlemen, Miss Romanoff," the foreign, disembodied voice of the so-called artificial intelligence that lives in the Avengers tower suddenly says. "Director Nick Fury on line 3 for you. It seems to be urgent." Tony groans into his steaming cup of the black beverage he is so fond of (coffee, he reminds himself, it is called coffee) and Steve sighs while Bruce rubs his glasses clean.
"Yeah, whatever," Tony replies. "Put him through."
It is another mission for the Avengers and Thor almost hopes it's his brother again because he misses him dearly even after everything Loki has done. They have always been together and it pains him greatly that Loki has strayed so far from the righteous path… Throughout Thor's life, Loki has been by his side, his best friend, his strongest companion. The center piece of the game that is his life. And now he's lost and Thor is slowly losing hope to ever get him back – and it's almost impossible to win a Game of Thrones without a center piece.
But it isn't Loki they are up against this time and while the Avengers battle another mad villain – Clint is shooting arrows and Natasha is firing her weapons with deadly accuracy with Tony flying high above their heads, distracting the enemy, and the giant green Hulk next to him while Steve throws his shield at yet another henchman – Thor watches them fight and realizes that while he has lost his center piece, he has gained five extra tokens in this insane game: Mere mortal beings, whose abilities exceed that of their own kind by a great deal.
They are mortal and deadly and they are weapons as much as guardians.
He feels that this game is not yet over and it's making him smile. As he throws Mjöllnir into the next enemy's face, he laughs and when the foul creature topples down, Thor knows he can win. Not only this particular fight but also the ones yet to come.
