Ron thought he'd heard her wrong at first, and frowned, blinking. She must've said something else. Either that, or Hermione had decided to play what had to be the first joke she'd decided to play on him in ages. He laughed then, nervously and because he didn't know what else to say to that.

"That's not funny, Hermione," he said.

It wasn't that having children with Hermione was something he didn't want— he reckoned they'd end up there eventually, since it'd come up between them briefly before now— but they hadn't even been married a month, had they? He felt like they'd barely settled into their new lives, it was too soon for a baby. So Hermione must've been trying to put one over on him.
