Avengers: Endgame: 15 fan theories so crazy, they might be true

15. Ronin gets an Infinity Stone
During the Avengers: Endgame Super Bowl spot, Reddit user ak2sup noticed Ronin is surrounded by a red glow in a cave. That sentence may not mean nothing to most, but they suggest that it could be linked to Thor: Dark World.
This cave could be the same place where Jane Foster found the Ether also known as the Reality Stone. Could this mean that there was some of the Ether left over? If this is the case, that means the Avengers have a slightly better chance in beating Thanos.
Crazy Scale: 5
We don’t know much about the Infinity Stones and what their real powers are. We do know a little bit about the Ether. Among them is they’re more fluid than the other stones. This means that there could be some of the Ether left over from when Sif and Volstagg brought it to the collector. We don’t know how the Ether works. For all we know, a small piece of it could grow and reach its full size over time. This is an amazing theory.
The Reality Stone is one of the more powerful ones. Used properly and the Avengers could trick Thanos into thinking the world around him is different. Giving the Avengers the opportunity to grab the rest of the stones.
