I have been reading a biography of Muggle Prime-Minister Winston Churchill and saw that he said the following:
"A politician needs the ability to foretell what is going to happen tomorrow, next week, next month, and next year. And to have the ability afterwards to explain why it didn't happen."
Never have truer words been spoken.
[Private to Oliver]
I hope that a night's rest has done you good, Oliver. I believe I may have a plan of attack, but it would require cooperation from both yourself and Melinda.
In my opinion, the best approach for you would be one that makes light of the situation. Casual jokes about "bewitching my cupcakes" accompanied by a knowing/playful wink, and in essence turning it into a great big joke. (This is, of course, an approach that would be impossible for someone like me, as the media/public would never believe me capable of cracking a joke or being anything other than serious with a, what do they say, stick up my arse?) The next step would then be to make an appearance in public with Melinda, give an opportunity for people to see you two together and genuine. The last step could be done with the assistance of Alicia, if she is amenable - you and Melinda using your current super-celebrity status for a fundraiser for the Fawley foundation, complete with desserts provided by Melinda's bakery.
The largest possible downside to this that I can see is that the media may in turn posit that this has all been a large publicity stunt to get increase awareness for Sweet Nothings, but knowing this, we can turn this in your favours because if it is 'just a stunt', then the media may possibly pay less attention in the future.
This will all, of course, hinge upon your ability to stick to the game plan, stay calm, and please Oliver, do not hit anyone off the pitch. If you don't care for my ideas, you're more than welcome to seek advice elsewhere - I hear Pansy Parkinson has made herself quite a reputation for her work in public relations and may even be willing to take you on as a client. Otherwise, I would be happy to sit with you both (you and Melinda, of course) to discuss this more thoroughly and prepare you both for the incoming media onslaught.
