Avengers: Endgame - 13 Major Questions After The Trailer

4. What Is Cap & Black Widow's Plan?

It's clear from Black Widow and Cap's vague chatter that they're preparing to hatch a plan to thwart Thanos, though the trailer doesn't remotely specify what this plan might be.

If the rumours are to be believed, Endgame will see the surviving Avengers travelling back through time in order to acquire the Infinity Stones for use in their own Infinity Gauntlet.

The obvious goal will be to undo the Decimation and defeat Thanos, and it's easy to see why Natasha and Steve look so wracked with fear and anxiety as they plot to execute their plan.

Like many of the scenes in the trailer, though, it's entirely possible this is a work of misdirection and the two are actually just preparing to pay Tony Stark a visit.
