Avengers: Infinity War - 15 Things Marvel Want You To Forget First
8. Pretty Much All Of The Avengers Post-Credits Scene
When It Mattered
Back at the end of the first Avengers movie, we met Thanos for the first time - very briefly - but what his immediate underling said about his plan was very telling. He referred not only to "courting death" but also to "challenging" humanity, who it turned out were not the walk-overs Loki had promised Thanos and The Other.
At that point, of course, Thanos turned round with a glint in his eye, seemingly responding not only to the challenge but also to the idea of courting Death, which would have fit in with the comic book telling of Infinity Gauntlet, where he attempted to seduce Death.
But Now...
Aside from him appearing, nothing in that post-credits scene matters, because it's most been retconned from relevance.
Firstly, there will be no courting Death as Infinity War will introduce Thanos' plan to wipe out half of existence as a well-intentioned attempt to rebalance the universe. Not to get him laid.
And secondly, why the hell was Thanos already thinking about challenging humanity at this point? His only purpose at this point was getting his hands on the Tesseract, which he promised Loki the Earth for (literally), which no longer involved humanity because Thor took it off planet at the end of the movie.
There was literally no call to challenge humanity: they were an insignificant side-concern, and for someone so apparently focused on rebalancing the universe, revenge would have been an illogical side-step. Plus, he didn't even follow up on the threat, so it's almost like it would have been better if it hadn't been written in at all.
