Bruce & Bobbi
"Huh? Oh..." Bruce was vaguely aware that shapeshifters were a thing that existed in the universe. He might have even heard that there was one running around and not really given it much of a thought. "I guess that makes more sense than Steve being here with Darcy though."
He hoped the conversation would deflect from his muttered comment since it wasn't his place to share that particular bit of news. Especially when he knew Tony was waiting until after the party to tell Darcy herself.
