I think it was good for Dia and bad for Amu. The state they're in right now probably feels like an improvement to the part of her that was Dia, but the Amu part likely found it painful.
Any idea what the bit about Easter headquarters could mean?
It seems like a memory from Amu...
So if we interpret that in the most straight forward manner then... Dia is Amu, thus if Dia remembers this, then Amu must have done this; despite so far I know never going there. It can't be a Dia separate exploration as she's only just woken up as well... and so far we know we've never lost sight of her with all the worrying over her we've done.
Thus in this super straight forward interpretation Dia must then have gotten the information from elsewhere some how.
Leading us to: (Or skip to the end if you don't want to read a lot of attempts to limit the possibilities)
- Dia is confusing this memory from some one else. But aside of Midori who would she have gotten it from? And would Midori ever have been in the HQ, and even if she did would she be so sloppy as letting those memories slip over? (Assuming it's not part of some further plan, but this seems potentially overly complicated for her... she's not one of the top players) No one else comes to mind as an option further, unless Dia can actually pull memories from other people, which would admittedly be an interesting discovery in and of itself, but would she really confuse those for her own? And who of the recently met people would actually have been there then? And why would Amu specifically only noticed those memories as odd then? As in, of all the memories she purviewed in the time frame she had, why did she only notice those as being potentially wrong? Other people should have given more inconsistencies one would think
- Alternately the memory is actually really from Amu/Dia, which is inconsistent, as she hasn't done that. Thus we must postulate alternate ways of how you could get a true memory. For instance it came from the Collective unconscious and that it carries all memories of Amu from all cycles (Speculative, is this really the case or possible?) Or alternately it comes from a previous cycle of this world and Dia survived it. (Considering this world seems to have been reset a few times this is possible, but it implies Dia survived the last end of the world some how. This is possible in theory though I suppose, considering the Nocturne plotline)
Splitting the two options of Collective Unconsciousness and surviving Nocturne or some other reset even apart:
- - Assuming the Collective Unconsciousness route, Every reset Amu's memory ends up there and Dia can access those... but is that actually really a real possible mechanic with in this universe? Or would each reset delete the CUs end data as well? I don't know, so I can't really properly evaluate this option. Still it seems possible.
- - To alternately survive the Nocturne plotline would have taken quite a bit of luck, it would require her to survive till the end and survive the new world creation event. Even with Dia being the most OP of chara, this would be quite a task. In such a world Dia might have been able to survive with out Amu I suppose... but she'd probably have picked up some deviations over time from that, just like the other Chara are now. This would complicate reconnecting with an Amu from another cycle one would assume. Or alternately Amu survived the event, and got till near the end... but that would still lead to a some what different Amu/Dia, which might complicate connecting to the reset Amu. Also in this branch you'd likely need the support of some one powerful, as surviving that world with out might be fairly challenging and surviving the world reset with out that could be quite difficult as well... though maybe Dia could some how trick herself through that? Still, if you had the support of say the winner, then they could probably pretty much wish any of these problems away in a new world reset. Thus it's possible I guess.
----
- A less straight forward explanation would for instance be that perhaps she's delusional or some such. Though one would think this might lead to more odd memories then just that one, and throw up more danger flags... Then again Amu is time pressed right now, so hard to be sure.
---------
Thus in summary I've managed via some logic to identify 5 possible interpretations at this point, specifically:
- Dia is confused about where specific memories she has are coming from and thus thinks other memories are hers. Amu how ever only notices one discrepancy when comparing with her own memories of events, perhaps due to time pressure.
- Dia is digging up past lives information from the Collective Unconsciousness, because seemingly she's Over Powered like that as well.
- Dia got help from the winner of a world reset event and got included in their wish. (Not so OP Dia theory)
- Dia managed to survive an end of the world event and its reset. And then either still has a connection to Amu afterwards because she's simply considered connected being her Chara, or managed to manipulate a new connection to Amu.
- Dia is Hallucinating up new memories or worse. Amu only notices one sign of it though, perhaps due to time pressure.
(To consider in these theories is that Dia had seemingly no problem reading the text properly that Amu couldn't, though this might be a Chara ability of hers)
