Fury lied about the origin of T'Challa's scars, and about T'Challa's history with the Weapon X Program, while also telling him that everything about the "Black Panther" was classified. Captain America eventually established a means of communicating with T'Challa and learned of the man's desire to return to Wakanda to see his father.
