Trapped

Clovis's expression turned serious. 

Because of the U-shaped web that Erwin made to trap him, he only had to go back first before being able to loop around. This might also be why Erwin was doing his best to contain him here.

Even Clovis wouldn't be able to go against them by himself unless he activated his unique state. However, no matter how hard Clovis tried to trigger it, he still had no control over that state. So Clovis had no chance of defeating them. At the same time, Clovis also didn't like to rely too much on the power that he couldn't control since it would cloud his judgment.

After looking at the situation, Clovis took a deep breath. Should he go to the side and break through the web formation? But doing so would pose a lethal threat, as there might be another hidden trick that Erwin had placed in there. 

In other words, the safest place was to continue ahead, even if it meant being surrounded by those five.
