Elsewhere During the Trial
Among the many servants to T'Challa and Ororo, most were not what they seemed.  One in particular, however, ventured out to gather supplies.  Walking through the streets of the capitol city, the human-form Skrull gave nervous glances every corner he turned.  The trial was about to begin, but the presence of the Avengers made him nervous.  There were not many Skrulls in Wakanda, and they did not have the backing of the Empire.
