He could almost feel the tension in her - not a Hulk thing, but knowing her for so long, instead. Bruce couldn't help laughing a little. "Nothing bad. At least, I hope you don't think it's bad." Because, despite knowing how much she loved him, there would always be that spark of anxiety. That bit of him that taunted and said he didn't deserve this.
He exhaled slowly and used his free hand to pull the ring out of his pocket. "I bought this almost twenty years ago now. I thought... I had it in my lab coat. That day. You know." Of course she knew. No one who'd been in the general vicinity would likely ever forget it. "I was going to take you out to dinner that night to celebrate and then....you know. The whole planning to spend the rest of my hopefully now superpowered life with you." His laugh was hesitant. Even now he sometimes wondered how it could have all gone so wrong. "I asked the Entity and, well, it came through. Same exact one. Because I think I've always known I'd need it again."
Pulling back enough so that he could see her face, his dark eyes searched hers. "It's been so long and still, there's nothing I want more in the world than to spend my life with you. We can't get all that time back, but we have here and now and I don't want to waste it. So...you know. What I'm saying is... Elizabeth Ross, will you marry me?"
