Earth-Bet meat machines ("humans") possess, use, and regain their equivalent of Willpower differently than people under Exalted mechanics. I use the OWoD ruleset as a guideline, but much of OWoD assumes magical shenanigans of some variation as well - which is not really the case here. For our purposes, Earth-Bet people generally have a pool of 1-5 Willpower (with some exceptions going higher), and regain it only after acting in accordance with their Nature Archetype or accomplishing a major goal. For example, Accord's Nature Archetype is Director:
Director
To the Director, nothing is worse than chaos and disorder. The Director seeks to be in charge, adopting a "my way or the highway" attitude on matters of decision-making. The Director is more concerned with bringing order out of strife, however, and need not be truly "in control" of a group to guide it. Coaches, teachers, and many political figures exemplify the Director Archetype. Directors may be simple advocates of established codes, or they may prove instrumental in tearing down corrupt existing orders to make way for new leaders or factional movements.
— Regain a point of Willpower when you influence or aid a group or influential individual in the completion of a difficult task.
So, in cases where Accord can apply his power and skills, he can recoup Willpower at a fairly rapid pace (compared to other Earth-Bet humans). However, his power forces so many
Intrusive Thoughts into his mind when he's out of his comfort zone that he can rapidly run himself dry in under a few minutes - Willpower to ward off such thoughts is
turn-based, not scene- or day-based for Earth-Bet folk. He's basically an edge case for Willpower use in Earth-Bet, but it's worth keeping in mind these mechanics for when the Twins start working their mojo.
Should he be given a soul and 'upgraded' to Exalted mechanics, not only would his Willpower give more bang for the buck, but he'd regain it much, much faster just sleeping and with minor Stunting.
