T'Challa and Nebula
"It was indeed a rough time for all," T'Challa exhaled, and he would go on to the next life still believing that Natasha didn't have to die; but she was here now, so that was what mattered. They should focus on that, and find a way to deal with the past that gave them peace. It was difficult to do.
But at a party, that was neither the time nor the place. His grin brightened again, considerably. "And yes, he is from this area - I am sure he'd regale you with stories of the way things were back then. At first I didn't agree with the good company," he chuckled ruefully. "But we have become good friends."
He thought he spotted Bucky in the distance, perhaps - so T'Challa would not intrude if he wanted to come this way. "Speak of the devil and he appears," the King laughed. "I ought to be on my way but it was nice seeing you, Nebula. May we meet again soon."
