When, in Philosopher's/Sorcerers Stone, first chapter, Vernon and Petunia are watching the news, the news broadcaster "allows himself a smile" right after he relates the news story about the owls being seen out in force in daylight... does he know what's going on?
Also in Philosophers/Sorcerers Stone, Harry has Hogwarts letters arriving in the oddest places, included being delivered by a very confused milkman by way of a bunch of eggs... In Chamber of Secrets, Colin Creevey tells us his dad is a milkman... could he be being used by the wizarding world to help deliver letters to Harry? I don't think, as I do with Lily, that Colin's parents are magical or squibs, but he obviously knows a bit about the wizarding world before going to Hogwarts (from day one he idolizes Harry, and he's excited about the moving portraits he's heard about)... This, I think, is a bit more unlikely than the newscaster, but still an interesting theory...
Any other well-placed characters we've seen and overlooked? Got any other ideas? Feel free to post them, and to offer your "yea or neighs" on the two I've listed.
