After Klaus' plea, he decided to give Gilbert one of the communication devices. He still had a few with him, so he didn't mind. It wasn't like he was using them anyway.
"What do you think about his abilities?" Grey asked the others after Gilbert left.
"Average." Klaus replied.
"It's because he didn't show everything." Grey said. When they were fighting, the group were the main fighters, Gilbert was a little passive. They didn't blame him for this since he didn't really have to fight any powerful opponent except the middle-aged man who suppressed him. Only after Grey took over did he have an easier time.
Grey went on to tell them some of the things he saw Gilbert doing and their expressions changed.
"Did you figure it out?" Klaus asked.
He knew how obsessed Grey was with things like this, so he couldn't help but ask.
