We have been getting all sorts of deleted scenes and extra knowledge about Black Panther because of its upcoming home release via digital download and Blu-Ray.

As reported by THR, in the commentary track on the blockbuster’s Blu-Ray release, Director Ryan Coogler what happened off-screen to Erik Killmonger (Michael B. Jordan)’s mother.

Before the events of Black Panther, N’Jobu (Sterling K. Brown), the brother of the king of Wakanda, falls in love with a woman in Oakland and they have a child, who grows up to be Erik “Killmonger” Stevens (Michael B. Jordan). It is through his love for Erik’s mother that N’Jobu changes his mind about the world outside of Wakanda, and decides he must help its people.

At the start of Black Panther, the audience sees N’Jobu and a young version of Forest Whitaker’s character, Zuri (Denzel Whitaker in the flashbacks), formulating a plan in an Oakland apartment.

“The idea was when you see those guys talking over the paperwork in the beginning of the film, they’re talking about a way to break her out of jail,” Coogler explains. “The idea was they never got her out, and she passed away in prison, so Killmonger didn’t come up with a mom either.”

This definitely makes the events in the film seem even more tragic.

Black Panther is available for digital download on May 8 and Blu-Ray on May 15.
