Sweetie
Background
Sweetie is a C-11 artificial intelligence system on the Trans Soma emergency medical rescue vessel Nightingale 229. Benj Sotomejor adapted her to have human-like emotions.
During the events of Supernova (2000) played by Vanessa Marshall
Sweetie wakes up Benj to play chess with her. While Benj and Nick Vanzant are playing cards, Sweetie warns him that he has a losing hand. Benj tells Nick that he illegally added human traits to Sweetie and after Sweetie tells him that Nick is likely to turn him in to the authorities, Nick assures him that he won't. An emergency distress signal is received and Nick tells them that the signal is five days old and is a direct call specifically to the Nightingale. Nick continues that the signal is from Pohl 6822, specifically the mining operation of Titan 37. Sweetie tells them that Pohl 6822 was expelled from its orbit and is now a rogue body. Sweetie then tells them that the sender of the SOS is Karl Larson. They arrive at their location and the Nightingale is hit by a debris storm and their fuel tanks are breached. Nick manages to keep the Nightingale from crashing and Sweetie tells him that they have lost 82% of their fuel and the dimensional drive will have to recharge.
Karl is brought onto the ship with an object and Sweetie tells Kaela that the object is made of extra-dimensional isotopic matter and is ninth-dimensional in nature. She says that dispersal of the matter would create new three-dimensional matter at the expense of current matter. Later, Benj tries to locate Yerzy Penalosa and Danika Lund, but Sweetie tells him that they are not onboard. Nick and Kaela run to the orb and Sweetie tells them that Karl has escaped and the orb has become unstable. After expelling Karl and the orb, Kaela and Nick run to the stabilization units and Sweetie tells them that the object will cause a supernova that will reach Earth in 51 years and either destroy life or create a new form of life. Nick and Kaela get into the stabilization unit and after the dimensional jump, Sweetie tells them that they have exchanged 2% of their DNA and Kaela is pregnant with a daughter.
