So many questions. Do her parents know? If so, why didn't they do anything?
Both scenarios are gross. I find it hard to believe she was able to pull the wool over her stepmother's eyes considering she's a psychologist, and her dad is probably skilled at reading people due to his glownigger training. If she was able to fool them though, she is an extremely dangerous individual.
The sad part is she's probably going to get away with everything. Even if she gets expelled both her parents are fucking loaded. She'll be able to manipulate either the dad or biological mother to get her some cushy job with their connections, if not outright support a NEET lifestyle. The Google factor and this thread might not even matter.
