Kode
Kode was a result of Fitz Kriener having his personality (and whole state of being) copied into a Remembrance Tank when he joined the Faction Paradox. Kode was the result of Fitz's personality being re-remembered throughout the time it took to travel to Earth through space. Therefore some of Fitz's personality traits had come through the process, the the Doctor recognised him as Fitz Kreiner (or Fitz's descendant). Like all members of The Remote he was open to all signals, as well as the TARDIS's, which made him more open to the Doctor's cause. Either through these signals, or the Doctor's Kode wished for the Doctor to restore him to who he was originally, based on the TARDIS's memories of Fitz Kreiner he was re-re-remembered using a remembrance tank.
