Bella Placed Locket in the Cave Theory WAS: Potion in the Cave

CH3ed:
I really like Carol's theory that: LV may have told Bella to hide 
his locket horcrux in the cave (without telling her it was just one 
of six horcruxes). And Bella, for fear of failure, took Kreacher 
with her in accomplishing the task. Kreacher then spilled the bean 
to Regulus/RAB, was forced by Regulus/RAB to help him replace the 
locket horcrux with a fake by drinking the potion (that resulted in 
permanently addled brain). Regulus then failed to destroy the locket 
before he died. 

It does neatly explain pretty much everything we see. My only 
problem is with Kreacher surviving that potion while Dumbledore 
probably wouldn't have (had he not get AKed on the Tower). But then 
Kreacher is a house-elf... and LV wouldn't have expected any such 
lowly creature (in his mind) to be able to penetrate all the way to 
one of his highly protected horcrux... so he might have used a 
potion that while fatal to wizards, is less so for house-elf? 

Also I hope that with Bella falling out of LV's favor, LV wouldn't 
think to check on the cave horcrux to hide it else where just 
because he no longer trust Bella much (seems like that hadn't 
occurred to him since the fake locket was still in place at the end 
of the year when Harry and DD found it, while we know of Bella's 
disgraced status in the beginning of the year).

CH3ed :O)
