- "Come on, David. Remember us. Remember yourself."
David Sedova is the husband of Olga Sedova. David was a bounty hunter operating in Neo-Paris before the prolonged abuse of his memories using Sensen technology resulted in the early onset of "Leaperism".
Like Olga, little is known about David's life prior to becoming a bounty hunter. He was born and raised in Ukraine. And likely made his name and career there before relocating to Neo-Paris. Early on his career, David became addicted to implanting memories of his targets he tracked in an effect to understand them and better track them.
Partnership with Olga Sedova
David and Olga met in Neo-Paris during the city's reconstruction. They agreed to help the government maintain law and order by catching criminals. Olga suggested that they join forces to better maximize their efforts in capturing the unlawful element of Neo-Paris.
Their partnership became famous in Neo-Paris, particularly during 2082, during the height of arrests of the Errorists. They arrested a record number of thirty seven Errorists and were awarded with the "Dead or Alive" award that same year.
Eventually, David's addiction began to worsen and he withdrew from the public eye. He was later hospitalized by Olga, who sought to get him treated at the Nymphea Hospital. Doctor Sebastian Quaid oversaw David's treatment, using memories transferred from Olga's Senwall into his to keep him stable.
Quaid believed the treatments but would, but were costly. When Olga received a wanted notice detailing Nilin Cartier-Wells escape from La Bastille Fortress, Olga acknowledged the cost of her husband's treatments and assured that she would able to cover them.
When Nilin remixes Olga's memory of David's treatment, she believes he's been killed by Memorize and Dr. Quaid. She sides with the Errorists and helps Nilin reach Mid-Paris. When Nilin asks for a guide, Olga mentions she has "family business to attend to", suggesting she planned on making arrangements for David's funeral.
Later, when she helps Nilin reach Mnemopolis in High Paris, she tells Nilin that they should have a drink in her husband's honor after she destroy's the Conception Cube. Olga's actions suggest that she never returned to Nymphea Hospital to confirm that David was dead.
The destruction of H3O returned and restored memories remixed using the Memorize's Sensen technology. As such, David's particular illness was likely cured as a result of his memories being restored.
