To be fairly honest,
Black Panther may have the most comprehensive and immersive worldbuilding in a blockbuster film since James Cameron's
Avatar. The world of Wakanda is full of masterful detail and culture, creating an experience unlike any other in the MCU. Like many Marvel films before it,
Black Panther has loads of Easter Eggs, including some that have yet to be unveiled. The lastest one may be small and trivial in the advanced utopia, but it remains to be heartwarming nonetheless.
During the scene in which T'Challa and Shuri are testing out new suits, a small Wakandan message is etched into the primary costume's abdomen. Posted on the Movie Deatils subreddit, an eagle eyed fan displayed some
insight into the discovery, translating what the text says using the internet,
In Black Panther, when T’Challa strikes the new Panther Habit suit to test its kinetic energy storage, some glowing Wakandan text appears on the torso. If you translate one chunk of this text, it actually says, 'I Love You Mom.'
Within the MCU canon this obviously refers to Angela Bassett's Queen Ramonda, but one can't help to think that Coogler is sending a message out to his own mother. Take from Coogler, don't ever be afraid to show love to your moms.
