Right after Marvel dropped a new "Captain America: Civil War" trailer on the world, members of the film's cast as well as its directors took part in a Q&A with fans as part of Buzzfeed's Answer Time. The cast touched on a wide number of topics, and co-director Anthony Russo elaborated on the state of Winter Soldier's (Sebastian Stan) relationship with Captain America (Chris Evans).

A fan asked about the most compelling aspect of Steve and Bucky's relationship, to which Russo replied:

"The relationship between Steve and Bucky is one of my brother's and my favorite aspects of the Captain America movies. It's so complex and tragic. They have a devotion to one another that is undermined and devastated by fate, and exploring how they endure that is fascinating for us as storytellers and fans. We feel 'Civil War' is the best chapter yet in the story of their relationship. The character has gone from being Bucky Barnes to being the Winter Soldier, and now in this movie he is something else. We explore whether he and Steve can ever have a relationship again and, if so, what that relationship can be."

Directed by Joe and Anthony Russo and starring Chris Evans, Robert Downey Jr., Scarlett Johansson, Anthony Mackie, Sebastian Stan and more, "Captain America: Civil War" opens on May 6, 2016.
