Avengers: Infinity War - How ALL 18 MCU Movies So Far Tie In

5. Doctor Strange

Mentions Of Infinity Stones?

The penultimate Infinity Stone was revealed with the MCU debut of Benedict Cumberbatch's Doctor Strange. It was revealed to be the power behind the magical Eye Of Agamotto, which could allow the user to manipulate time.

There's also confirmation that the Sorcerors know all about the Infinity Stones and how dangerous having two in one place could be - just as the Warriors Three and Odin did in Thor: The Dark World. Somehow, Thanos knows he has the Stone, since he seems to send the Black Order to New York specifically to target it.

Relevant Story Details

Doctor Strange not being entirely comfortable with his powers should probably come into play, especially as he's going to battle as big a threat as Ebony Maw and the mentions of the multiverse will presumably come back to relevance as well. Though again, who knows how.

The biggest thing to take from Doctor Strange is that the Avengers now have a means to time travel - and thus a means to undo anything catastrophic that might happen to them at the end of Infinity War...
