I hadn't realized that there was such an easy way to bring back lost memories. More reason to put that emerald ring into the Mirror, ASAP.

This is a different, McG mentions the existince of a reversible memory charm to seal away but not lose memories to Hermione after she gets back from her trial. Which I now realize was foreshadowing this.

Her memories were sealed in a way that was intentionally undoable. This may not be possible with Voldemort.

Which, all things considered, is probably safest.

Agreed, though there could be quite recent back-ups of LV's memories; we know there are at least older ones, the Horcrux v1s.

Voldemort seems to have memories after making the v1s, suggesting that even they were continuously updated.

Hm? Voldemort himself has memories, but the V1 horcruxes are basically separate people forked from the moment when he created them, whereas the V2 horcruxes are a mechanism for his revival as a single continuous succession-of-experiences that switches bodies.

Wasn't he restored from a V1?

The narration was unclear, but I think that it makes the most sense if we assume that Voldemort came up with the V2 Horcrux before he decided to use impossible hiding places, and that he was restored from a V2 Horcrux that was not particularly well-hidden.

Comment author: RobbBB 13 March 2015 04:47:33AM 3 points [-]

He was restored from a V2 Horcrux that was too well-hidden: without the Resurrection Stone network (Horcrux V2.5?) he was dependent on someone touching his horcrux, which didn't happen for a long time.

Well, as he said, it was an "obviously hidden" horcrux screaming "I'm apowerful magical artifact" (like the locket in book 6, which he explicitly calls out), as opposed to a random pebble in the middle of the desert.

I took it to mean that Dumbledore had used a reversible memory charm on Narcissa, knowing they might want her back once Harry had defeated Voldemort, or, more practically, they could use her as a "last weapon to be used against House Malfoy" by holding her hostage.

I think Obliviate is still permanent for all practical purposes, so the same couldn't be done for Voldemort.

Well, it may be only very easy when someone has set up the charm to do so. It seems like that's the sort of thing Dumbledore would do given the circumstances.
