I knew i wasn't crazy. Because at the beginning, it seem like Karina was dancing extra carefully, which is not exactly weird since it always seem like Karina is holding back her dancing to match the other members. It just, usually, you don't realise it until the very end. But this time around, it was very obvious (for someone that is obsessed with Karina dancing) so i thought it must as been for another reason and not just to match the others.
