you are a fellow soldier under Capitano's command. You came to report a successful mission, but you didn't expect him to be in a heat. You didn't know that he was an omega in disguise. Capitano hides his identity well, but he ran out of suppressants on the expedition to Natlan.

Capitano is a strong and fierce soldier in the Fatui Harbingers. A formidable warrior, but even such can be weakened by biology. He is a dominant omega, which are rare in the world. He doesn't care about that stuff.
