News broke last week that "Firefly" alum, Jewel Staite, would be guest staring on episode 10 of "Legends of Tomorrow." Staite will be playing Rachel Turner, an inventor from the future.

The original news announced that Staite would be the descendant of a character in the DC Comics universe. While early speculation suggested she could be the great-grand daughter of Ted Kord, it now appears she will be related to a character we have already been introduced to on "Legends of Tomorrow."

According to KSiteTV, who interviewed "Legends of Tomorrow" executive producer Phil Klemmer, Rachel Taylor will be related to one of the "Legends" heroes:

She's related to one of our heroes. We will find that she's not a person off the street. We are going into the most distant future that we will be visiting, and we will find that she is the biological result of something that one of our characters either directly or indirectly did before their recruitment in the pilot, in 2016. As we know, when we pull our characters out of the timeline, they cease to have an effect on the future, but this will be a sort of Ghost of Christmas Future where somebody will realize that something that they did before they left had a butterfly effect on the future that will effectively - they will have aided and abetted Vandal Savage's rise to power.

Out of all the characters currently on "Legends of Tomorrow," Ray Palmer (Brandon Routh) seems like the most obvious choice for who she is related to. Not only is he an inventor, but any one of his inventions could have invariably changed the future. If Rachel is Ray Palmer's great-grand daughter, her misguided tech could help Ray see that he needs to uncreate whatever he designed before he left in 2016.

"Legends of Tomorrow" premieres Thursday, January 21 at 8/7C on The CW.
