Coogler felt having this symmetry was important.[150] In the scene, T'Challa says "The foolish build barriers, while the wise build bridges." Some felt this was a reference to the political climate of the presidency of Donald Trump, but Coogler stated that the line was added before Trump's election and was simply an African proverb that his wife had found. His intention with the scene was to inspire the audience by making T'Challa seem like a real person in a familiar, real-world environment, similar to how Tony Stark was treated in Iron Man (2008).[151] Coogler was not mandated by Marvel to feature connections to other films, but was interested in addressing the fact that Barnes was in Wakanda (per the end of Civil War) because it would be fun for the audience.
