Call Enzo and Pedro
Stella and Adrianne's eyes widened in panic. They did not realize Amy had been in the crowd throughout the whole exchange. She had recognized the three women to be the same ones who had some sort of misunderstanding with the two women last time.
Well, it wasn't a misunderstanding anymore. Amy had gotten the full scoop from the exchange and was just waiting for the right moment to intervene. First they insult her friends, make ridiculous allegations against her and even took her pictures! This was not a good time for her face to be caught on camera!
So she stepped forward, used the crowd surrounding the blonde woman as an advantage, and struck the woman's armpit with the side of her open hand. She had once read on pressure points and learnt that this would make the person's arm go numb and they will briefly feel pain from the impact.
