Cass just watched at the far end of the room as the other knights tied up Helga. She regained consciousness but couldn't resist.
Gilbert confirmed that the bonds were strong enough to hold her. They honestly didn't know if the bond could hold her back considering she could just disappear like light.
But after making sure Helga didn't disappear, maybe this time she was weak.
"We'll take care of her tomorrow. Now let's clear up the mess outside." Gilbert was referring to the servants and guards who had fainted. It seemed they were given a drink or food that made them that way.
Gilbert and the others started to leave. While Cass remained standing there. She leaned against the wall, watching Helga struggling to move. Her mouth was gagged and her hands and feet were chained with steel. She wouldn't be able to get away so easily.
"Coming here is like committing suicide. I don't understand why you can think that you can beat Felix."
