It's possible that Lore (Brent Spiner) becomes good in Star Trek: Picard season 3. Lore is the evil twin of the beloved Lt. Commander Data (Brent Spiner) introduced in Star Trek: The Next Generation season 1, episode 13, "Datalore." He immediately showed himself to be murderous and duplicitous and Lore returned to menace the crew of the Enterprise throughout TNG. Lore was dismantled and destroyed in TNG season 7, episode 1, "Descent Part II" but somehow, Data's brother is back in Star Trek: Picard.
However, Lore could learn to act differently in the next season of Picard. Many things have changed in the almost 30 years since the events of TNG. His brother, Data, has died. However, Star Trek: Picard season 1 have upgraded androids into more human-like synthetics like Data's "daughter," Soji (Isa Briones). And thanks to the heroics of Admiral Jean-Luc Picard (Patrick Stewart) and his motley crew, synths are no longer banned by the United Federation of Planets. This could give Lore a place to belong, something he has been lacking. That is a powerful reason for any person, including synthetic ones, to consider changing their behavior.
Data's Death Can Motivate Lore To Turn Good
Data's physical body was destroyed in Star Trek: Nemesis, but his consciousness lived on. At the end of Star Trek: Picard season 1, Picard turned off Data's consciousness at the android's request, effectively allowing Data to die. While Lore had betrayed and harmed Data, he did so because he felt that Data should join him in his quest for power. This means that, on some level, Lore cared for his brother. Data's iconic death in Picard could provoke Lore to self-reflect and act differently.
Most of the cast of TNG has already been confirmed to join Picard season 3, and they could help Lore to work through his brother's death if the android will allow them. After all, the crew of the TNG Enterprise is the closest thing that Data had to a family besides Lore. Being around people who loved Data so much could lead Lore to reflect on his own existence and whether he wants to be remembered as the darker part of Dr. Noonien Soong's (Brent Spiner) legacy or embrace the more giving legacy of Data.
Evil Lore's Return Doesn't Fit With Star Trek: Picard's Synth Message
Lore's potential transformation is made more likely by the general philosophical trajectory of Star Trek: Picard. Jean-Luc worked throughout the first season to get the Federation to lift the ban on synths following a deadly attack on Mars. Picard proved that the villainous Commodore Oh (Tamlyn Tomita), a Romulan mole in Starfleet, was really the one behind that attack, not the synths. Soji is working to change the overall perception of synths, as seen in the premiere of Star Trek: Picard season 2. Having Lore remain evil would undermine that message, but redeeming him would bring that story full circle.
One way to achieve this would be to have Lore help the Federation and the synths within it. Picard season 2 left the ultimate fate of Commodore Oh unresolved. Helping the TNG crew resolve the damage she did and rounding up her and the rest of her co-conspirators could be a way for Lore to begin building a new, better legacy. It would also help Lore gain the trust of Picard and the TNG crew since he had only ever harmed them.
Android Picard Can Finally Relate To Lore
One of the primary motivations for Lore's actions throughout TNG is that he feels that he is in a class by himself. This usually comes out in arrogant speeches about his superiority to everyone, including Data. However, there is an undercurrent of loneliness and longing in the way Lore speaks and acts. Jean-Luc Picard, now being an android and one that is made with superior technology to Lore, could give Lore pause. He is no longer alone. He is no longer the best - if he ever really was. Perhaps in Star Trek: Picard season 3, he can find people with whom he truly belongs.
A meeting between the two will provide the perfect opportunity for an iconic Picard speech about legacy. In season 3 of Picard, the Star Trek Admiral may understand Lore the way he couldn't before, and that will make a powerful speech even more convincing. Lore could be convinced that he can continue to be superior by choosing to be magnanimous and not lording his gifts over others. It is also demonstrably in his own interest to act morally, given how recently the synth ban was overturned in Picard. It is reasonable to assume that people's attitudes will change more slowly than the law, and evil machinations by Lore will reinforce that synths are evil. Lore has been dismantled once, and that can happen again.
Lore Can Replace Data In Picard Season 3's TNG Reunion
All of TNG's main characters reunite in Star Trek: Picard season 3. This provides an opportunity for closure and for Lore to step into Data's shoes. Lore is Data's twin brother but can't replace him entirely, of course. Picard and his crew will need to trust him, which will take time or some act of heroism by Lore. However, it's not an insurmountable challenge, especially since the TNG crew will have an incentive to forgive him, as he is Data's brother and Data is gone.
Lore will no longer be alone in the galaxy if he embraces his brother's legacy and his brother's found family, in turn, embraces him. Transforming Lore from a menacing threat in TNG to a hero in Star Trek: Picard will also fit with the show's legacy of neutralizing historic enemies, such as Q (John de Lancie) and the Borg, through cooperation and friendship. Allowing Lore to be redeemed in this way would be honoring a major trope of TNG and a theme as old as Star Trek itself of resolving conflict nonviolently and seeing the good in all sentient beings.
