"Apparently when we were in Hawaii..." Dick began, actually glad for the distraction from his proposal plans (there hadn't actually been any, but it was going to be hard convincing her of that). "Apparently in Hawaii we... met a couple named Barry and Iris--" It would have to be Barry and Iris, didn't it? Perhaps Ralph and Sue were otherwise occupied. "--and they were the witnesses at our... wedding."
The word scared him, not because he was afraid of marriage as such, but because he knew that Carrie was. Which was why he'd been working on a place to hide the ring until she wasn't terrified by the prospect. And just his luck that she should find it before he'd moved it.
