May and her friends backed away when one of the men repeated what they before she answered them. She watched as the stranger got in front of her and bantered with the two scary people in front of him before a full out fight started. What was especially unnerving was the mention of Scarro and having her power. 
She stayed back and she could only watch as the fight continued. May noticed electricity and metal and came to the conclusion that one of the men was using a taser, and she called to David, "Don't let that taser hit you! Watch out!".
