When (clone) Shiro is placed in a suspended animation pod, his right shoulder is drawn in the shape of the Paladin armor, but colored as though it's his robotic arm (which is shaped like a normal human arm, not like the pointy shoulder pad of the armor).
Keith gives the order to form the sword, then inserts his Bayard into the Black Lion's console. The sword is formed by the Red Lion's pilot inserting their Bayard, not the Black Lion. It should have been Lance forming the sword.
