We have know for a while that Avengers: Infinity War will be part of a focused Hulk story arc spanning 3 movies and we are starting to see small pieces of how the story might unfold in Infinity War. According to a recent CBR article, Banner and Natasha will continue to develop their ongoing relationship. Is it just Natasha helping Banner revert from a Hulk out? Will the Banner/Natasha relationship become something more?
Another article from screenrant hints at a possible meeting between Banner and/or Hulk that leaves a strong impression on our favorite Jade Giant. The story is more speculation than anything but posits that the scene at the end of Ragnarok with the Guardians of the Galaxy might have been the group encountering the mad titan himself.
Mark Ruffalo: The Hulk is also mightily impressed by Thanos.
These articles leave more questions than answers but it does seem to confirm that the Hulk will have a nice story within the movie. I suspect that MCU won’t give too much away so we will have to wait and see what unfolds in the movie. The images below (click to enlarge) and articles are worth a quick look and don’t really spoil anything.
