As luck would have it, Christy Xenos and Ethan Zhekova were both targeting the same person.
They both struck at the same time, causing a greater effect than anticipated.
If it had been just one person pushing, Wendy Clarke, though thrown off balance, would have been able to regain steadiness.
But now with both of them pushing her simultaneously and thinking that they might fail if they didn't exert enough force, they pushed as hard as they could.
The force was much more than Wendy Clarke anticipated.
She was completely taken aback, having believed that they were on her side, and Christy Xenos was the only opponent unaware of their plan.
She had not anticipated any hostility from either Ethan Zhekova or Christy Xenos.
As a result, she was sent flying by the combined efforts of the two and didn't even have a chance to stagger back.
She fell, sprawled in the middle of the road.
