Shuri hadn't forgotten the offer to go into space. How could anyone possibly do that? She was just running behind because that seemed to be her life right now. Trying to figure out what had happened to the Captain and Dr. Banner was taking a lot of her focus. She tended to lose track of time.
Arriving on the roof of the Avenger's Tower reminded her a little of Wakanda. The ships stored here were beautiful, and one of them was her goal.
Her hair a la Princess Leia, sort of, and casually dressed in shorts, sneakers, a denim jacket and a t-shirt that declared 'Life is Beautiful!', Shuri jumped up and down and waved at what she hoped was a spot on the Benetar where someone would see her.
