When Luke disappears why doesn't his metal hand remain?
When Luke disappears into the force world why doesn't his robotic arm replacement stay with the robe? You would think you would hear it clink as it falls to the floor and hits the ground but it looks like it also disappears with him. Why is that? It's not a part of him. so that confused me.
Yoda and Obi-Wan disappeared completely but there were no robotic parts on them.
