SPOILER WARNING: The following story contains possible spoilers for "Avengers: Age of Ultron.

We had a few big questions regarding the next big Marvel Studios blockbuster following the release of the first "Avengers: Age of Ultron" trailer -- and it looks like Mark Ruffalo may have just given us an answer.

In a set interview with IGN, the man behind the green beast touched upon Bruce Banner's possible relationship with Scarlett Johansson's Black Widow.

"Uhhh, we don't have a relation -- What kind of relationship?" Ruffalo initially responded, unsure of what details had already been revealed. " [To Disney representative] Did you tell them that?

Ruffalo may have played it coy, but one scene in the "Age of Ultron" trailer supports the idea that Bruce and Natasha could be more than just teammates.

All questions will possibly be answered when "Avengers: Age of Ultron" opens on May 1, 2015.
