In the previous episode titled "Los Muertos" of AMC's horror-drama series "Fear the Walking Dead" Season 2, after getting drunk in a Tijuana bar, Madison Clark revealed several information regarding her past to Victor Strand. However, the most shocking one came as Madison being a resident of Alabama.

Most of the "Fear the Walking Dead" fans are those who have been fans of the original series, "The Walking Dead" on which "Fear" is based. Hence, it didn't take them much time to realise that apparently, Madison is the only character in the series who is from the southeastern part of the country, where the incidents of "The Walking Dead" take place.

The speculation has given spark to rumours that there might be a crossover between both the shows in the future. Also, fans have been speculating who Madison might be related to in "The Walking Dead."

In the original comic books, on which both the shows are based, Rick Grimes has a brother who goes by the name of Jeff. There is a significant possibility that Madison might be Rick's sister and during the plague, got separated from him. Her name might have been changed after her first marriage.

Though the theory sounds interesting, neither Madison nor Rick have ever mentioned each other's name in any of the previous episode. Hence, the show-runner might come out with a plot that will tell a past story where the two got separated in a tragic turn of events.

However, talking with Comic Book, Dave Erickson, producer of "Fear," clearly said that as of now, there is no plan to merge both the shows together.

"As of right now, no, there is no plan," Erickson said, "From a narrative perspective, never mind the geography of it all, I think it would be too difficult to pull off. I don't think there's anything, as far as I've read in the comic, I don't think there's any track-way for that either. It's such a complicated proposition and I think for the time being, the two shows just need to exist in their own spheres."
