DID isnt the only personality disorder that creates alters tho. OSDD and PTSD are possibilities. Depending on the OSDD they can share memoriest. DID systems dont share memory but they can do memory bleed.
I forgot to say but since aparrently the two personalities integrated, there will be memory assimilation. Alters resulting from integration recieve memories and sometimes the role from the pre-existing alters before the integration.
I don't think this hyung has a DID syndrome, coz he wouldn't have fragments of memories from the other persona if he really has a DID, and there are many personality disorder that we didn't know of, well this is my opinion.. please don't hate me if your don't agree on my comment.. again this is just my opinion..
