In 2024, Redditor StefanMorse identified Spanish model Leticia Sardá as a likely candidate by running a colored-in version of the print through the facial recognition tool PimEyes.

[10][3] Some prominent speculation focused on potential lookalikes who were also popular around the same time period, such as Olivia Wilde of House or Taylor Kitsch of Friday Night Lights, but matching photographs could not be found.

[9] Redditors found that the curtain came from the Finnish department store Anttila [fi], appearing in its Summer 2009 catalog, and that it was supplied by Látky Mráz in the Czech Republic.

[9][11][r 2] A Spaniard who occasionally participated in the subreddit, IndigoRoom, then contacted Leandre Escorsell, who had photographed Sardá for the cover of a 2006 Tendencias ('trends') insert in the Spanish magazine Woman,[a] and asked if he recognized the print.

[9][13] As of her identification as Celebrity Number Six, she was working as a waitress at a café, living, in her words, "a quiet life with my children, my little house, my little job", far removed from her past as a model.

[13] Sardá told Vanity Fair that she used Facebook to stay in touch with four friends and occasionally browsed Instagram, but was not active on Reddit and LinkedIn, where many people were contacting her.

[9] She created accounts on a number of social media sites[7] and expressed interest in making TikTok videos, saying that if going viral became an issue, "I can always hide.

[7] On 15 September, Sardá hosted an AMA ("Ask Me Anything") on r/CelebrityNumberSix, in which she expressed that, after adjusting to the shock, she was "having fun" with her sudden fame and thanked the subreddit's members for having changed her life.

Kurt Luther, director of the Crowd Intelligence Lab at Virginia Tech, expressed optimism that those investigations would be resolved, crediting the diverse set of skills that amateur sleuths bring to their communities.

[3] Solving "esoteric, low-stakes myster[ies]" like Celebrity Number Six has become, according to journalist Caitlin Dewey, "something of a participant sport" on social media, like "catnip for a certain type of Reddit user".

[3] Angela Watercutter looked at the role of AI from a different perspective, characterizing the authenticity dispute, and similar speculation that "Ulterior Motives" had been AI-generated, as showing that "the internet is now even more untrustworthy than it used to be".

He reasoned that as generative AI becomes increasingly able to create images that look like real photographs, the proliferation of such deepfake will "dilute the conversation" in future searches.

[11] Koebler also remarked on the use of traditional journalistic methods, with Celebrity Number Six ultimately being found "with a combination of AI facial recognition software and one photographer's long memory".

Club called mysteries like Celebrity Number Six "one of the last great bastions of the early days of the internet", but speculated that they would become less common in time "as the world moves further away from not just physical media but reality itself", citing the use of AI-generated images in ads for the film Civil War and in the documentary What Jennifer Did.
