Avengers: Age Of Ultron - 10 Biggest Surprises That Will Get Fans Talking

10. Banner And Romanoff Sitting In A Tree

To its credit, the Marvel Cinematic Universe has thus far shied away from making Black Widow anybody's romantic interest. She definitely looked to be at risk of that, both with her introduction around infamous ladykiller Tony Stark in Iron Man 2 and what was essentially a co-lead in Captain America: The Winter Solider. For the most part, though, Natasha Romanoff has wielded more autonomy than most female franchise heroes would. Which all goes out the window a bit with Age Of Ultron, when it turns out she's got the goo-goo eyes for Bruce Banner. She plays a similar role to the first film when the team are in the field, but back at Avengers Tower things are different. The bumbling scientist assumes she's just flirting, and is resistant because of his... anger issues, so it's all the more surprising when they actually lock lips. Even if it's just for a second before she pushes him off a cliff.
