Some images from the Atlanta set of the still untitled fourth Avengers movie have been posted over at Page Six (via Atlanta Filming on Twitter), and they feature Robert Downey Jr., Gwyneth Paltrow and Mark Ruffalo in character as Tony Stark, Pepper Potts and Bruce Banner.
At first glance there doesn't appear to be a whole lot to the pics, but on closer inspection they may hint at some fairly major plot SPOILERS.
For one, Pepper is wearing an engagement ring which obviously implies Tony popped the question and she said yes - but there's more. As you scroll through the photos you'll notice that Tony and Pepper actually appear to be saying farewell, and that final shot of Banner hugging his fellow Science Bro definitely suggests that things are getting a bit emotional.
Is Iron Man about to head off on some kind of mission he's not expecting to return from, perhaps? Check out the images at the link below and let us know what you think.
