"Let's do it! Kill that idiot!"
"Yeah, kill those b*stards! If they're not gonna let us live, we'll fight them to the death!"
"Yeah! Let's slaughter this kid first! Then we'll seize Carldish Fort!"
...
The former members of the 13th Division were incredibly fired up, some of them even claiming that they wanted to seize the fort. Though Jiang Fei was brave, he did not dare proceed with that suggestion.
Instead, he had a very simple plan in mind. All he wanted was to force Aino to make an appearance. That's why he had taken Trakus hostage. Once Aino was here, Jiang Fei would use his position as Theon's apprentice to negotiate with him. He wasn't even asking for much, just to save the lives of Sarila and the others.
