Prologue
T'Challa focused on his piloting skills as he listened to the fully awake passengers. Zemo was very subdued he had tried to kill himself outside the bunker in Siberia and he had stopped it. Steve Rogers and James Barnes were talking quietly amongst themselves. T'Challa had wrapped up the left stub as best as he could; he knew as soon as they landed, there would be a team of highly specialized doctors meeting them to escort Mr. Barnes to the med bay with Mr. Rogers following right behind. Zemo on the other hand would be handed over to his loyal guards, so they could put him in a jail and then hand him over to Vienna authorities where he would face criminal charges of not only killing his father but also killing the psychologist who was supposed to interview Mr. Barnes but instead he initiated Mr. Barnes control words, which in turn severely injuring three people and injuring five more. T'Challa knew now it wasn't Mr. Barnes fault. Being controlled for 70 plus years and knowing who you killed after getting your memories back from not being under HYDRA's thumb. He knew it would cost Mr. Barnes psychologically but emotionally as well.
T'Calla came in for a landing in Wakanda, he started thinking of someone who could help Mr. Barnes eradicate the trigger words that enacts the Winter Soldier but also walk through his emotion state as well. One name kept coming to his mind: Annie Martin. She had her B. A. (Bachelor of Arts) in Psychology and an A.A. (Associate's Degree) in teaching. Annie's psychological degree was hard especially working under a man who thought humans were pawns in his chess game. T'Challa didn't know how she survived under Strucker's teaching but she did and gave him heck for his ideas; not only did she do it in her thesis but to his face as well. She had called him an ass (donkey) for his ideas for turning amnesiac patients to his will so that could be robots and do his bidding. T'Challa's ex-wife *Storm had acquired Annie's thesis and had agreed with Storm's assessment when he read the file; Annie Martin would be a good teacher for the children of Wakanda.
When they hired Annie and introduce to her to the children, she was upfront and honest with them. She expected to be honest with her as she would be with them. Annie expected the same honesty from adults because as she explained in her interview that children picking up if you're being honest or not. More often than not adults tended to water down the truth or not explain at all and that was not how she was going to be with the children and she expected the adults to straight up and honest with the children not sugar coat it for them. T'Challa knew that Annie would be great for Steven and James.
T'Challa landed the plane and escorted his guest to their accommodations.
