When everyone heard Isabel's declaration, they put up their guard and waited for Derik's reply. They were all aware of Derik's fierce the fallen archangel, Samael. A being which they doubted Isabel could stand against! But Derik did it, moreover, he sent the fallen archangel running with his tails between his legs. This kid cannot be compared to his peers and is considered a monster by anyone who has a deep understanding of his abilities. If he should battle them right now with all he has, even if they team up and overwhelm him with sheer numbers, they weren't sure they will come out of the battle unscathed. Obviously, they will suffer major losses on their side. This is why they all held their breath at this moment waiting for his reply, even Elsa felt uneasy and anxious at this moment, staring at Derik with pleading eyes.
