There are two end credits scenes, but one is much more cryptic than the other.

Were going all in with this one.

This is aSPOILER HEAVYarticle.

So allow us to explain.

But all that is secondary to the way the characters describe the Tesseract and the Aether.

In the scene, they specifically refer to them both as Infinity Stones.

In case that doesnt mean anything to you, lets back up a little.

Anyone holding all six has the power to reshape the entire universe to their will.

Its safe to say theyre pretty desirable, not least to power-mad alien warlords.

Once he had them, Thanos mounted the gems onto a glove that became known as the Infinity Gauntlet.

The Aether is acting like the Power Stone, which gives the holder access to unimaginable energy.

But where is this going?

But Robert Downey Jr. has signed up forAvengers 3.

Were guessing, of course.

It could be a stand-alone movie, it could be aGuardians Of The Galaxysequel.

Maybe they havent even decided what theyre doing with any of it yet.

But one way or another, the Infinity Gauntlet movie is coming.
