The spiritnof death is alive and is present in the city. Clark saved people from dying because, frankly, it waasn’t their time but death loomed over his aunt and it eventually took her. She was dying of cancer and there was nothing Clark, in all his might and with all his power could do. She passed away knewing that Clark was Superboy and has been and is doing great things. She was proud of him and he defended her against Lana and her criticism.
