As with all Marvel movies, Thor: The Dark World contained an end credits scene. Two in fact, but only one was important to future movies. It’s also probably the most confusing to mainstream audiences thus far. Whereas other “stingers” were clear references like Thor’s hammer at the end credits of Iron Man 2, the reference during the end credits of Thor: The Dark World probably left a lot of non-comics fans scratching their heads.
In an attempt to clear some things up, I’ve put together an explanation of the scene, and you can read it after the jump. Obviously, this explanation contains spoilers.
