Han's story
So to put it, Han went to Tokyo met up with the Yakuuza, in between teaching Sean, he must of met with Mr. Nobody, rescued Elle, then stole from the Yakuza, so he could protect the orphaned Elle, faked with death by replacing himself with a hologram.
Though never fully explained, but I think the "real" Han confronted DK and secretly replaced himself with his hologram (so the RX7 must have been a remote control?) or like Cipher, he used his car as a drone BTS and watched his "death" from afar.
