Katia is usually pretty stand-offish, shutting herself off from others, afraid they get to close to her and pierce through her tough exterior. Zack, seeing through her facade, matched her energy and called her bluff.

After weeks of dancing around one another, flirting and challenging each other, the tension reaches a new level. As Zack swings by to grab some stuff for his sister, he and Katia connect, on more levels than one this time. What follows is a steamy, passionate night.
