I didn't go by spoilers this week . . . it just seemed like the Ace/Sugar/Matty alliance was strong and mutually beneficial to all involved.  Sugar turned on Ace who'd had her back the entire game to vote with 2 people who have no use for her now.  
Dan (can anyone say needy) was complaining, whiney and annoying everyone at camp and just seemed like the obvious choice for Kota.
