Thanos' cosmic war is headed to Earth, but love might end up conquering all. Although Avengers: Infinity War will feature every virtually every Marvel Cinematic Universe hero, from Star-Lord to Spider-Man, it will find time to once again explore the complicated love story between Bruce Banner and Natasha Romanoff.

During a visit to the Infinity War set by Screen Rant and other outlets, actor Mark Ruffalo revealed the relationship between the Black Widow and his character will once again come into focus. "They're star-crossed lovers, so it'll be something they're dealing with for the rest of their lives," he teased. "Whether it's requited or unrequited, I don't imagine that's gonna go away any time soon in one iteration or another."

The relationship between Banner and Romanoff stood out from their first meeting in 2012's The Avengers. In Avengers: Age of Ultron, they tried to make things work as a couple as best they could, a subplot that some fans considered a disappointment in the 2015 sequel. However, the recent Thor: Ragnarok showed the bond between Widow and Hulk is still strong, given that the mere sight of Natasha's recorded video was enough for Banner to transform back into his human self, after spending more than two years as the Jade Giant.

After years apart, it will be bittersweet to see these two characters reunite, especially considering the circumstances surrounding their last encounter, during the battle of Sokovia.
