Kaitlin entered the Big Brother 15 house and quickly became friends with the worst people in the house.
She surrounded herself with Aaryn and Jeremy who she quickly also had a showmance with.
I dont know if it was partially because of the surprise first 2 votes but Kaitlin, Aaryn and Ginamarie basically were the mean girls in the house.
Not only was Kaitlin a mean girl who hung around with a couple of the worst houseguests off all time, she also seemed kind of bland as far as actual personality goes.
She was evicted in week 4 and has become a fairly forgettable character from the show.
