The bullet destroyed the object that created the shield, allowing the thrown gun to hit the mayor in his arm.
Stanley hadn't realized just how hard and how fast he had thrown the gun. While obviously nowhere nearly as fast as the bullet, the gun he threw was still blazing fast.
Because he had remained in slowed time even as it reached it, he hadn't realized that. So, when the gun crushed the man's arm and nearly tore it off from his limb, he was surprised.
How was that possible?
Even with his strength, it shouldn't have been possible to throw something so hard. Was it because the time was slowed down?
As the urgency of the situation died down, Stanley instinctively let the time flow back to normal.
The glowing red sword in the mayor's hand had slid off to the side without touching Sheila, so she was safe. She was still screaming in pain as the broken limb nearly made her go unconscious.
