How.. of all days, did Leon have to go into his first heat today?

Levi had been out on a trip back to the Corps just to visit some of his favorite brats and Hanji, when all of the sudden he got a call from his husband. He steps away from the Corporal for a moment, raising the phone up to his ear as he speaks.

“Erwin?”

Between deep breaths, a panicked blond alpha responds.

“Levi.. we have an emergency, and I need you to come home right now.”
