hahaha
if needed, Ryu can just power down, makes his body lighter for others to help him, but ironically the silver supports his muscles so he can walk better on his own
oeh I know

he will shift the silver so it covers his face (due to the cops) as its currently, and supports his legs so kevin has it better, but his upper body is lighter in general so Kevin and he can walk together.
he just needs someone to support his body due to the dizziness

EDIT:
to make things clear, his power comes out of his spine, so from the center of his spine will be a line to his legs and head
