When Hektor saw Alex carrying a dead Richter, Hektor instantly knew what happened. He couldn't believe it, but the truth was right in front of his eyes. That monster of a leader, the one whose ability to read ahead was so absurd that he seems to be psychic. That leader whose strength was so ridiculous that it was practically cheating. That fearsome leader that had all of them dancing in the palm of his hands has died.
Though he had a hard time accepting it, Hektor had not time to dwell on that matter. All he needed to know was that Alexander Samarita was the victor.
When Hektor thought of that, he immediately adjusted his understanding of Alex, this kid in front of him was a true blue monster. The chances of him winning against someone who killed Richter was close to zero, even against an exhausted Alex the chances were slim, coupled with the fact that he could team up with Oliver and the others, this made winning practically impossible.
