He hesitated for a second, not because of their awkwardness but because of the rest of it -- it wasn't like infertility was a thing you just popped up with, all "oh hey why can't you have a kid?" (And even if he could, he wouldn't do it that way.) But at the same time, it was a question he wanted to know, albeit his brain had phrased it much more tactfully even for his own wonderings.
Thankfully, his brain unscrambled itself after that brief second and came up with the words he hoped were appropriate. "So -- and I apologize if I'm asking this badly, please tell me if I am -- how... did you realize it wasn't going to...?"
Not smooth at all, Phil, but intentions earnestly meant nonetheless.
