"I have five hundred and eighty six shekels." ... welp!! That's just the money she has on her right now, yes. Best not to ask where it came from, since almost all of it was very likely obtained less-than-legally, probably from people who do not need money anymore. Since that's more than enough money for the two of them to get into trouble, and Laura has little need for money on her own, well. She'll allow Kiden to drag her wherever and spend her money on terrorizing the citizens of Baedal.
