maybe he was an experiment for El-dorado along with Rei Rukh and both tried to escape, on their way out the door was closing so Rei pushed Fei so he could escape and yelled out something to do with soccer, like "Let's play soccer", before the door closed and Fei tried to get through the door to Rei but didn't work and began to cry then saw that El-dorado was looking so ran as far away as possible and then met Clark, while Rei was captured again and continued to be an experiment for El-dorado. Just a thought, sorry if it's long.
