Late at night, unable to sleep, Bruce found Tony looking at some footage from the battle. More specifically at some footage of him turning into the Big Guy.
"What are you doing?" he asked, his voice soft with an edge of cautious wonder.
"Look at that." said Tony before asking JARVIS to rewind the video until there was a close-up, a one meter high version of a face, seemingly caught between him and the Big Guy.
"Look there, the eyes, they are just the same color as mint syrup. How cool is that?"
Bruce chuckled ackwardly and tried to find a way to find this "cool". He couldn't and left silently as Tony was still going on about his eyes couleur menthe à l'eau.
