The Missing 24hrs!! Maybe....

Dumbledore tells Harry that Snape is the one to go to when you need help regarding the Dark Arts, like if you have been injured by a curse....

Dumbledore goes to Snape sometime during the summer between Harry's 5th and 6th years. He's injured while destroying the ring horcrux, and he goes to Snape (still at Hogwarts, possibly about to leave for Spinner's End) for help.

When Katie Bell is injured by the opal necklace, a cursed object, McGonagall has Filch take the necklace to Snape for inspection.

What if this is a clue about the missing 24hrs after the attack on the Potters?

Imagine this senario:

• Voldemort attacks the Potters. James dies from an AK, Lily makes her choice and dies by AK, and the AK cast at Harry backfires. Other things happen, too, like the house falling to ruins.
  
• Someone is there to witness the attack and quickly informs Dumbledore.


• Dumbledore sends Hagrid to get Harry out of the house and tells him to take Harry to Snape for inspection. (We're definitely dealing with a dark curse here.)


• Hagrid shows up at Godric's Hollow, meets up with Sirius and borrows the bike, then takes Harry away from the crime scene before the Muggles show up .


• This brings Harry out of Godric's Hollow (wherever it is) and takes him to...well, Spinner's End, perhaps? The clues about Spinner's End suggest either Wales or the environs around Manchester... However, Snape tells Bellatrix he was at Hogwarts, and since it was the middle of term at school, it makes sense for Snape to be at Hogwarts, not Spinner's End...unless Dumbledore asked Snape to leave the castle and go to Spinner's End (or elsewhere) to help him....


• Snape observes Harry for several hours and possibly performs some tests (like a healer or doctor would), then he contacts Dumbledore to say that, except for a nasty cut on his forehead, Harry seems healthy and can be placed with his relatives. (I'm assuming here that Snape has at least some idea of Dumbledore's plans to place Harry with his aunt... and might know about the blood magic Dumbledore uses to seal Harry's protection at #4 Privet Drive.) Alternate senario: Harry's injuries are more severe than a cut on the forehead, and Snape stops the spread of something, much like he later does for Dumbledore and Katie Bell....


• Hagrid then takes Harry from wherever Snape was to Surrey. Like Moody in OotP, Hagrid might take a winding route, trying to throw off the enemy....

Freaky idea, but plausible. Nowhere in canon does it say Hagrid went directly from Godric's Hollow to Privet Drive in Surrey.
