Future episode where the Paladins encounter and help out a technologically advanced alien race who dabble in the world of prosthetic limbs, much like the Galra, but they only issue the prosthetics when needed. They also have a synthetic skin they've created and offer to cover Shiro's robot arm in said skin.
Shiro accepts the offer and the skin bonds with his own, covering his arm and creating fingerprints, fingernails, as well as adpating to the melanin in his human skin. It has a sensory input that Pidge can't wait to study back at the castle.
Shiro's finally able to feel warmth in his right hand again, able to touch Keith's face without causing him to flinch at the cold metal of his fake fingers. Shiro finally feels a little more human again.
