Spoilers...?Sounds like there is a lot of speculation that Filoni and gang are picking up a bunch of old George ideas and recycling them in this show. One idea comes from a cancelled Darth Maul video game:
https://starwars.fandom.com/wiki/Battle_of_the_Sith_Lords"George Lucas revealed his interest in Darth Maul working with Darth Talon, a concept that would carry over to Lucas' first drafts of the Star Wars sequel trilogy.[10] When Lucas was told that this would not work since Talon lived more than 170 years after Maul, he said the main character could instead be a descendant or clone of Maul.[11] Talon's purpose in the game would have been to serve as "Maul's Lauren Bacal", a smart and sexy female deutagonist.[8]"
So, flash forward to the Maul Shadow Lord preview from SWJC where it was shown that Maul is training/working with a red/pink skinned Twilek. There is a ton of speculation over whether of not this may be his new apprentice and so all the rumor-folks are assuming that she = "Darth Talon" because of the video game stuff above.
