Shandra didn't want to leave Ali, but she knew he wouldn't be able to keep up or outrun a human. "I love you. And I promise to wait for as long as I must," she said, as her tears started to fall. Giving Ali one last loving nuzzle, she fled.
Shandra heard the discharge of a human gun, but kept running, even as her tears began to flow more. She assumed Ali was dead, and knew she had to escape from the human.
Ali slowly got to his feet, and coughed up more blood. He walked over to the human and finished him. Ali let out a howl and then coughed up more blood. He collapsed and coughed up blood again.
