Kingpin

Does anyone with Santeria knowledge know the meaning behind Lupita mixing her blood with paint, and then painting her brothers face? This was at the end of the episode. Also, what is the significance of the three coins on the chain? Overall it was a boring episode, too much time spent develping Brian Benben's character, but hopefully it will heat up in the next episode. The lead actor, Yancey, is reason enough for me to watch...meow!
