.... Okay, I've got nothing. They are.. still in the mirror?

Dumbledore was acting very strange. The part of my mind that spits out theories is going "If Dumbledore can employ future-scrying-based planning techniques, please fuck off, I refuse to anticipate the plots of gods"

Edit: After bullying my imaginary voices. for a bit:

...I'm not at all sure Dumbledore was even there! Arrgh. "Illusion" is way up there in the plausible theories range. A whole ten percent or so.

The cloak is an obvious counter to a mirror trap.. But Dumbledore put the cloak into play. So... the cloak is trapped, somehow? .. dying while wearing it would shield him from his own hocruxes or something?

It was supposed to shield Harry in the event he ran the gauntlet?

Gah.

General Theory; Dumbledore generally uses shot-gun plotting. Not just one plot, but many plots aimed at the same end. he has applied that principle to taking out Voldemort.

Still don't think "Flamel" is dead.
