Who was evicted on Big Brother 15 tonight in week 4? The official results are finally in but we pretty much already knew who would go home on Big Brother 15 this week way before the votes were counted. Going into the CBS live eviction show last night, the outcome was pretty much already a given thanks to Big Brother 2013 spoilers from the Live Feeds.

A massive vote flip took place earlier this week, totally switching the house from a solid plan to evict one HouseGuest to target another eviction nominee entirely. While many of the fans who just watch the network show and/or Big Brother After Dark may have been expecting one particular ‘Mean Girl’ to go home… it was actually one of the other two who who was the first girl to go home this season. So who was the HouseGuest who was voted off Big Brother last night? Read on for the scoop on how the vote came about and who got the boot on this week’s CBS live eviction results and Head of Household episode. WARNING: This post contains information from the 2013 Big Brother Live Feeds on game play, competition results, vote discussions and other Big Brother spoilers not yet aired on the CBS network TV show, as well as the official results from Thursday night’s live eviction. Please stop here if you do not want to know!

We were 99.9 percent certain that the person we would be saying goodbye to on Big Brother 15 tonight would be Kaitlin, one of the three girls in the fan-named Mean Girls alliance. Ironically enough, all three of the so-called Mean Girls were up on the block together this week: Aaryn, Kaitlin and GinaMarie. When Head of Household Judd originally put Aaryn and Kaitlin up for eviction this week, copying Helen’s nominations from the previous week, it seemed extremely likely that it would be Aaryn going home. However, the America as Most Valuable Player twist, Elissa’s eviction nomination and her subsequent Power of Veto Competition win shook things up inside the Big Brother 15 house. People began talking, and thinking, and scheming.

Eventually, the power group in the house (Helen, Elissa, Judd, Andy, McCrae and Amanda) decided to push a vote flip to get out Kaitlin instead of Aaryn — although Elissa has been extremely reluctant and could possibly throw a rogue vote against Aaryn. They brought Jessie on board and worked on Candice, Howard and Spencer in various ways (sometimes through false and real side alliances) to get them to vote with the house. Once the house was already moving into alignment, Aaryn was brought in on the plan to evict Kaitlin as well, in exchange for certain loyalty promises. By Wednesday, it was all pretty much a done deal. Kaitlin would be out and Aaryn promised that if she won the Head of Household Competition, she would do Helen and her allies’ bidding in choosing her nominations. (Not that anyone should actually believe her.) Nothing much changed on the Big Brother Live Feeds on Thursday morning to indicate anything else would go down.

So once again, a major vote flip changed the whole house around in just a week from targeting one HouseGuest for eviction to voting out someone else entirely. Here’s how the official vote went down tonight:

Amanda: Voted to evict Kaitlin.
McCrae: Voted to evict Kaitlin.
Helen: Voted to evict Kaitlin.
Candice: Voted to evict Kaitlin.
Elissa: Voted to evict Kaitlin.
Spencer: Voted to evict Kaitlin.
Howard: Voted to evict Kaitlin.
Andy: Voted to evict Kaitlin.
Jessie: Voted to evict Kaitlin.

With a vote of 9 to zero, Kaitlin was evicted from the Big Brother 15 house in week 4.
