Albert Ashbourne's affliction first began on the day after he left the Imperial Palace. He had successfully reported his discoveries in the woods regarding the undead creature Feeral without exposing the truth that he had found a girl lying beside it.
When he was on the carriage on their journey back to the manor, Albert had a small attack. Gilbert was alarmed and changed the carriage's course to go find a doctor to help cure his dear friend. However, the findings of the doctor was a mystery as Albert was without any wound nor infections. Rather, he was as healthy as a horse, making his sudden screams filled with pain a mystery to all.
Fortunately, the first attack stopped minutes after the doctor had arrived. He was asked about it, however, Albert was even more confused and shocked of what had happened to him.
