As Ramone was a former member of El Lobos, Crowbar demands to know where Ramone stands now. Mother Windom, an elderly shopkeeper, dresses down both Crowbar and Ramone.
Two of the Skulls threaten Windom with knives. McCabe, as the Vixen, and Zatanna, intervene. When one of the Skulls draws a gun, Ramone uses his vibratory powers to shatter the weapon, and subdue the gunman.
