Vectis walked up to the bus and was about to take Chleo off the bus and kill her. He wanted to rip the girl's heart to ensure her death with his own hands.
He had been gathering the energies remnants of the rulers for a long time so that he would have the unlimited power to fight Aslan. And the only one most extraordinary energy remnants he had ever gathered was Chleo's crimson soul, which had once received a life energy transfusion from the Flame Queen.
But unbeknownst to him, time in this world was reversed and Chleora Regnz came back to life without the energy transfusion of the Flame Queen. As a result, the red soul he had obtained in the previous life began to fade, and some of it had entered Chleo's current body.
Thus, he had to take Chleo's soul once more and return some of the red souls that managed to escape to its origin.
