BioGrey lives together with his wife Hannah and Flabebe near Ebine Town. His wife recently fell ill and was admitted to the Central Hospital of Ebine Town. He was told that Hannah had to be hospitalized for a while. The next morning when he woke up, Flabebe was gone.
He had a hunch and went to the hospital Hannah was staying in and he found Flabebe in the rain, watching Hannah with a worried expression. It got startled and dropped its flower which was crushed by a passing vehicle and a strong gust of wind blew Flabebe away. He been looking for Flabebe the whole time and was finally been reunited when he saw it resting on Bonnie's hair.
He went to stay with his wife at the hospital after Ash and friends said they'd look for a Fairy Flower for him. Grey and Hannah were both thankful that they were able to get the flower and both Hannah and Flabebe were on the road to recovery.
