Okay. Let me be straight forward with you and tell you that I haven't seen Avengers: Age Of Ultron yet. So no spoilers here, but... This is my theory that I came up with...
The Woman In The Cave
Now, I first got thinking when I read an article a while ago, and unfortunately, I do not know Professor X, where I might have him be able to pry my mind into remembering what that article was and who wrote it so that I could share it with you guys. But basically, it talked about how the woman in the trailer (shown below)
Might actually be Death herself, which could somehow tie into Thanos being in the picture of the Avengers MCU.
Which leads to the fact that Thor MIGHT die in the movie.
That's right Thor. Well, he might not die, but get hurt, or, even have his powers neutralized, considering the fact that, well let me go back a little before I explain how this might be possible.
In this bio, it says that Ultron was discovered as a simple computer program hidden among the ruins of the Chitauri invasion. So as you see here,
Thor is accusing Tony Stark for messing with a species he doesn't fully understand, and he either
- probably goes to Asguard to figure out what's up.
- Or, he may be going on hiatus for a while to visit his homeland. You never know.
And so when he gets to Asguard, someone/something harms him or takes his power,
landing him in this pool that the mysterious woman is in,
It's just a thought.
BUT she also may be Shuri, Black Panther's sister. Which ties Black Panther into the MCU. This pool-ish looking area might as well be a vibranium mine, considering the fact that Ultron coats himself in it.
Well, anyways, those are my thoughts.
