Except that...has anyone
actually entertained the thought that Aqua seeing an illusion of Terra specifically has nothing
to to with the conversation between Naminé and the Lingering Will at all and that Aqua's time in the RoD is not restricted to only the part where she is at Castle of Dreams?
Aqua's entire time in the RoD encompasses the whole timeline from the end of BBS up to the end of DDD. The illusion of Terra at Castle of Dreams may be indeed just an hallucination on her own part, also considering that the whole thing drags her spirit down instead of up apparently
It is entirely possible that Naminé is referring to an entire different incident that we haven't seen yet and that may or may not be actually a part of 0.2 at a different point in the timeline.
If we go indeed by the premise that the whole meeting between Naminé and the LW takes place in the post-CoM/Days part of the timeline then that indicates Aqua might eventually truly "touch" whatever there is of Terra in the LW during a different situation in the RoD that does
take place in the post-CoM/Days timeframe, totally unrelated to the illusion scene already shown in the 0.2 demo.
So instead of letting the head steam like a hot boiler and cringe at how it doesn't make sense maybe it is better to look at the whole thing from a different angle and do not weave a connection between two incidents that actually to not even have a connection?
We haven't yet seen very much of what Aqua will actually encounter throughout the whole of KH 0.2 and I do not recall that it has been actually implied anywhere that this meeting between the LW and Naminé is actually directly tied to Aqua seeing that Terra illusion (which may very well originate from her own
memories playing a trick on her due to her current state of mind) at Castle of Dreams.
This is a solely fanmade association, an association that may not even be there as elaborated upon above.
