I am confused about the name of the title. I have watched Grimm upto the latest episode, but I still don't understand this title. I watched this episode a dozen times and it still doesn't say anything about Sam Bertram being a Fuchsbau. So why do they name the title "THREE COINS IN A FUCHSBAU" ?

PLEASE HELP ME UNDERSTAND.
