As long as she looks like an honest and innocent person on television episodes, perhaps she feels like she’s protecting her brand, though she’ll learn when she gets out that’s not really the case.

Nicole was dropped by several sponsors due to live feed footage that showed her and others mocking Ian Terry’s autism weeks before she’d play a part in his eviction.
