BB16 Update 8/22/14: So, Frankie went insane and maneuvered so that Zach was in position to be "evicted" (eliminated from the game) on Thursday, August 21. It was unnecessary - Frankie was actually in a position to ensure Zach's safety for another week, but he chose to sell him out instead. On top of that, Frankie has been trashing Zach to other House Guests, including telling some vicious lies. I'm pretty disgusted with Frankie right now.
Zach was evicted last night. He managed to make his departure entertaining (showering his fellow house guests with Froot Loop confetti) and charming (presenting show host Julie Chen with a flower).
