3. An Independent Wales

Marvel Studios

The first post-credits scene is effectively T'Challa's "I am Iron Man" moment, as it will lead to him uncovering Wakanda's secrets (those that the non-idiots who've seen the Panther in action and realised they're not what they seem anyway haven't worked out). This presumably happens at the same UN meeting we witness in the mid-credits.

As the eagle-eyed members of the audience would have noticed, that UN meeting had a bit of a problem. Well, not a problem - more of a curious revelation.

Because apparently, in the MCU, Wales is an independent country with their own representation in the UN - which is why their flag appears among the delegates. Score one for Welsh Independence!
