What I wouldn't have given for that Memory to have been real. I was so bent when I found out Namine and Roxas were nobodies. And we (the public) don't even know if it will be called 'Kingdom Hearts 3'. Aqua,Ven and Terra are going to have their own series but it has a realtionship via connecting storyline to Kingdom Hearts.
Also very sorry if you knew that, just most people consider A,V and T Sora,Riku and Kairi, sometimes Roxas's too and if they would READ the daily news coming from offical Kingdom Hearts sources there wouldn't been any confusion on who is who.
And sorry for ranting, that just annoys me on how some (Keyword: some) can be so dense in the brain stem.
