i think that the bhk is the physical incarnation of the memories that namine implanted into sora.maybe she created him to fill the place that sora left vacant at the end of CoM? what do you think about this. this incarnation of memories theroy does not make the bhk a copy of sora but some thing like a brother maybe. parts of them related to each other but both of them unique
If you are against the Riku/Sora pairing, copy this into your signature.
Riku and Sora are straight
Get it through your thick skulls!
-finally! thank you monsoon
