 Falk felt that virtual reality undermined the show 's " strong connection to reality " , and suggested that after so many dangerous incidents Dr. Quest would have turned the system off . Writers brought back several classic characters , including Pasha the Peddler , Jezebel Jade , and Dr. Zin . Falk honored Quest creator Doug Wildey by creating an eponymous grandfather for Jonny in the episode " Nuclear Netherworld " , as well as homage to William Hanna 's birthstate of New Mexico where Jonny 's grandfather resides . The team created Estella Velasquez as Jessie 's mother to retcon the telefilms , feeling that Jade would never get married . Writers eventually killed off villains Ezekiel Rage and Dr. Jeremiah Surd in favor of new adversaries . Comparing Quest without Zin to " James Bond without S.P.E.C.T.R.E. " , Falk penned a season finale featuring classic robot spies and a visceral fight between Dr. Quest and Zin . Falk planned to resuscitate Palm Key as the Quest home in new episodes . Cartoon Network did not renew Real Adventures , despite a pledge to explore the history of Jonny 's mother Rachel in the season premiere .
