ok but did Steve have any clue what to do with the shields Shuri gave him at first?

T’Challa knows Steve’s signature is a shield, every picture of Captain America shows his shield, he saw Steve with the shield, but does he have any idea how he used that shield?

Steve had a red, white, and blue frisbee he was flinging at Nazi’s and robots and thinking ‘cool’ as it would bounce back to him, then he’s given these fancy elongated things on his arms, Shuri rattles off how they work, T’Challa has a fond smile,

But Steve’s just standing there and staring at his arms, wonder ‘What the fuck am I supposed to do with these things’
