Dumbledore and Polyjuice

Oh I am not suggesting Dumbledore knew Bella and Cissie were coming to 
Spinners End. It was an event that happened and had to be dealt with.

But a thought on Dumbledore's unexplained injury.

At Spinners End Snape enters into an Unbreakable Vow. The description 
of The UV here specifes that the participants clasp right hand to 
right hand and at the climax of the oath the clasped hands are 
enveloped in a swirl of fire.

Now my speculation. Dumbledore has been spying on Voldemort assuming 
Sapes form, using Polyjuice. He is searching for Horcruxes. In this 
Polyjuice speculation  Cissy and Bella unexpectedly confront 
Dumbledore/Snape at Spinners End. Dum/Snape finds it necessary to go 
through the unbreakable vow procedure to carry forwards his overall 
mission. 

Maybe Bella has a Horcrux in her posession -a  ring perhaps?

Later we find Dumbledore with a fire-ravaged hand - and it is NOT 
specified whether this is his right or his left hand as far as I can 
see in any Canonical Text. Text-Experts - can anyone check out the 
ravaged hand references in HBP?

What would be the effect of Dumbledore re-assuming his own form with 
an oath like the UV impacting on it even though the oath was taken in 
Snape-Form? Maybe combatting the immediate influence of the UV caused 
his hand to be ravaged by magical Fire? 

OK all speculation - but the circumstances of the Ravaged Hand MUST 
form part of the core Text in Book 8 or all the hand references in HBP 
are padding.
