Dr. Who's reality (Dr. Who and the Daleks)

One of the possible parallel universe versions of the Tenth Doctor drawn up by Gabby Gonzalez's "magic" notebook resembled (COMIC: Four Dimensions) the version of Dr. Who who had a niece called Louise and a granddaughter called Barbara in addition to his granddaughter Susan. This suggested that his reality was a parallel universe relative to the Tenth Doctor's. (NOTVALID: Dr. Who and the Daleks, Daleks' Invasion Earth 2150 A.D.) However, other accounts of how this Dr. Who related to other versions of the Doctor existed. (PROSE: Unnatural History, The Five O'Clock Shadow, etc.)
