' Tony.. there was no other way '

I took it that from all the possible future outcomes he saw that giving Thanos the ring was the only outcome in which they came out on top (kind of like in Men in Black 3 when Griff told K and J that the only outcome that was successful was the one in which they told the MP's the truth).

I forget how many possible futures did Strange say he had seen? I know it was a lot.

In the comics, it's usually Thanos' own hubris that defeats him, not the heroes, so letting him form the Infinity Gauntlet does seem to set him on the path to defeat.

time crystal? it was the time stone. not crystal.

Well i thing to it's impossible to Dr. Strange sees possible outcomes which happens after his death despite the power of time stone. Even his astral projection will be vanished after his death.

The whole Dr. Strange 14m outcomes part is there just to confuse watchers. He let's Thanos to spare Tony live because he knows his importance for survived humans on Earth. Loos of Tony could be devastating to us and whole universe so it's clever to trade stone for Tony life instead of to be stubborn and leave Thanos to kill everyone to get the stone.

That one winning scenario is the one in which Quill doesn't affect the "taking the gauntlet off" part of the battle. But even the time stone can't predict everything perfectly 'coz of chaos theory.

Sir--- a standing applause for hitting on the KEY LINE in this movie.👏👏👏👏

Your analysis of the future movie was correct.

Your talents are truely wasted here.

As everything worked out the way it did, there really was no other way. Alternate realities are a sham as cause and effect are real.

"But that comment from (spoiler) a soon to be dead Dr. Strange is extremely intriguing. It can be taken as a resignation of defeat, that this was the only path taken in the 14+ million future battle scenarios that he envisioned."

SPOILER SPOILER SPOILER

If Strange really has seen all the possible futures and has sorted out which one is the only one that'll work... then he knows damn well that the Infinity War ends with Tony dying and himself surviving.

So he gave that crystal to Thanos to save half the universe, let himself get snapped without regret because he knew he'd be back, and gave Tony a regretful look because he knew that he was working towards an outcome where Tony died.
