People really care about the crowd reaction? lol
Lateysha was there for the interview, she could have had her friends and family there to start the chant or boos.
Also, it was eviction. Ryan, Hughie, Sam's friends and family could be there as well. A crowd of 200+ people really isn't a majority of vote tbf. Why do people always assume the crowd reflects the British public?

It's mostly the friends and family of the potential evictees there..
