For some reason, Primrose was absolutely certain that the kissing part wasn't actually necessary. It was probably just Edmund's sneaky way of getting her to kiss him from afar without having to ask directly.
She couldn't be completely sure, though, because Edmund was doing his best to think, [My head is empty. I think nothing. Empty ... empty ... my head is empty.]
And usually, whenever her husband tried that hard not to think about something, it meant he was trying to hide it from her.
Still, it seemed harmless enough, so Primrose decided to follow his instructions without arguing.
"Alright, I'll give it a try," she said.
She closed her eyes and leaned down to kiss the gemstone on her ring three times, then whispered in her mind, 'I want to see my husband.'
She repeated those words a few times until suddenly—despite her eyes being shut—she could see her surroundings.
