This morning during ABC News, Letitia Wright, who plays Shuri in the MCU came in to promote Avengers: Infinity War. While she didn't reveal anything about the movie, there was a brief clip shared that featured Black Panther’s younger sister scanning Vision and talking with Bruce Banner (Mark Ruffalo). In the process, she makes it very clear that she is much smarter than him.
She won't reveal if she interacts with Tony Stark in the film or not, but it would be interesting to see him get schooled by Shuri, who schools Banner in this clip.
I also included a new TV spot for the film, which features a bit of additional footage of Spider-Man as he asks Tony Stark to clear a few things up for him because he's a little confused about the situation that he's found himself in.
Avengers: Infinity War hits theaters in less than 10 days! The anticipation is killing me! If you want to skip to the clip in the video below it starts at the 4:18 mark.
