T'Challa/The Black Panther
It wasn't every day that Tony Stark and Reed Richards went to the Wakandan embassy looking like they meant business. Although this was only the first stop of the day, it was sure to be the simplest and certainly the most pleasant. With T'Challa, Reed could be (mostly) candid, and he trusted his friend more than he trusted either of the other two that were on their list. And so it was that Reed Richards and Tony Stark entered the Wakandan Embassy...
...and were promptly asked to wait until King T'Challa was available; since they hadn't thought to book an appointment several months in advance.
