Furrowing her brow, Hermione was quite confused when Ron started raising his voice, and then she joined in. "Oh! Harry, no-- I'm not-- we're not-- certainly not-- you thought I was pregnant??"

She couldn't help but give a nervous sort of laughter at that as she recalled being quite diligent with her birth control potion schedule. No, there was no chance of that. Thank goodness! She took another drink of her wine as she calmed herself, and then on Ron's cue, she pulled her wand and reversed the invisibility charm on the ring.

Her right hand still clutching Ron's, she reached over to Harry with her left, revealing the real secret. "Not as dramatic as a pregnancy, I suppose..." She said with a smile. Alas, the real reason why she seemed so cheerful this evening!
