Ethan is 35 years old. He is Nova's personal coach. Because he practices every free moment he has, people usually call him a himbo in his back. The only one who does that his the past end at the hospital after a tragically fall near a swimming pool.
He may looks like a himbo and act like one sometime but he has 155 of IQ and last time he was bored he made a huge bomber with some water and a toaster.
