So, I was chatting in the car with my parents on the way back from seeing the movie. I was an emotional wreck for the obvious reason of Bucky and Steve CRUSHING MY HEART.

However, we began talking about what Strange said, about their odds of winning. He went through 14 million (?) scenarios in the future and came back with 1 that they could win.

Now, we know Strange was not going to give up that Time Stone for a guy he just met, no matter what he was meant to protect it. But here’s the thing, what if the reason he’s giving up the Time Stone is because he knows what has to happen for that 1 chance of winning to work. Strange is a smart guy, he’s not just going to give it up because he knows what the consequences are. Thanos might get what he wants for the time being but it doesn’t mean he has won.

I think the quote Strange says before he disappears off the top of my head was “It has to be this way.”
