In another reality, the cards fell differently.
Shiro’s escape doesn’t go quite as planned and Ulaz is forced to take him in his own escape pod back to the Blades of Marmora- where he meets the first human face he’s seen in a year: Keith.
Keith’s mother left him with the Blades instead of back on earth. He’s never seen another human being before Ulaz brings the Champion back. Fascinated, Keith is immediately and, to Shiro’s awkward discomfort, very personally curious about him.
Defending the Universe was never going to be easy, but now Shiro has to juggle his new duties with his memories of the Arena and an overly-tactile alien-raised partner with no concept of basic human etiquette. Thankfully for them both, Keith is the key Voltron needs– and the one Shiro needs, too.
