sorry i had to make this for GTX. in DD and ASAS there are only 2 unknowns. believe i have played through and beaten kingdom hearts 2. and not only are the not just concepts, but they are replayed in the game in worsened graphics. . so yes DD/ASAS actually happen in KH2. and also you already know who the 2 unknowns are. BHK or Roxas is GEU and Sitting unknown is Riku. also the unknown on top of the building is riku as we all thaught before. and the one below is Roxas. dont worry though as this ruins nothing of the storyluine i actually seem to remember this being quite close to the beginnning of the game. but dont take my word for placement in the game. Also i would love to say that i posted this theory long long ago that there were only 2 unknowns in DD and i got flamed major for it and now im right so there, all you flamers. and yes when he's saying he looks just like you he's talking about sora and he's talking to BHK
