Calvin (David Cubitt) has been a thorn in the side of most of Virgin River's residents since the show began. As the head of a large-scale cannabis operation, Calvin is also the rough-around-the-edges leader of a local gang, who even tried to induct Brady (Ben Hollingsworth) to help drive a rift between him and his longtime friend, Jack. Calvin and Jack have clashed on multiple occasions, but it's never been revealed who the real mastermind behind Calvin's operation is, until now. 

Jack has been gathering investors for his airstream rental business, and Nick (Keith Mackechnie) was one of the first people to sign up. When Nick invites Jack and Mel to join him and his wife for dinner, his sister stops by to pay him a visit during the get-together, and whoa! Nick's sister is the mysterious blonde behind Calvin's drug operation. Now that we know who she really is, it doesn't paint a pretty picture for Jack's new business endeavor.
