They found him under one of the rock crevices. He was bold and quick. He snarled at them, but he wasn't big enough yet.
Over the years, Leo had grown up to be a star attraction. He had been sent from zoo to zoo and landed in a circus finally. He was an intelligent animal and wasn't hard to train. Unlike other lions he learned quickly, in other words; he didn't put up much of a fight. The trainers never saw anything odd. They were just happy that their job was a lot easier with Leo.
Leo knew his routine well, so well that he could do it with a blindfold on. This made the trainers trust him even more. They'd feed him well before a show and let him enjoy the freedom other animals couldn't.
One night Leo was practicing with his trainers. The next day was going to be one of the biggest shows ever. Leo had to enter the arena with a bang from the bottom. He then had to run around the arena growling at the fans. Later, he had to run towards the trainer and jump and keep his paws on the trainer's shoulders and walk with him. After which he had to jump through some hoops and play football with the elephants.
It was going to be the last night, he thought to himself. He had had enough of this life.
With the stands filled with roaring crowd, it was Leo's turn to entertain everyone. He entered the ring and growled at the audience running around. This ended up making the audience roar even more. He started running toward his trainer. He was not running, he was charging. But the trainer was too relaxed to notice this. Leo took a jump and in an instant the trainers neck was in Leo's grip. He had killed the trainer in an instant. The whole crowd launched into a frenzy. There was chaos everywhere. They all ran for their lives.
Leo had done the unthinkable. He had killed the man who owned him and now he was free. He looked back at the circus tent as the people ran out of it and then he never looked back again.
