I couldn't pass up the trouble that Marcone marrying a girl who looks all of 18 will cause for him! Harry will certainly be accompanied by her Guard, and will furthermore expand it later - the only question I'm wrestling with is, 'How does she get Bob?', because Harry without Bob is just unimaginable.

And of course! An un-oblivious Harry is hardly Harry at all!
[and I don't suppose you have any suggestions for the title?]
