He had taught his son all about being the trusted advisor and mentor to the Te Xuan Ze of his time. When his mate had died of unknown causes, he remained the trusted advisor and ally to Jasmine as she grew older. William was the advisor before Monroe.
Season One[]
He dropped by at the Lee home as he was being watched over by Barbara who was taking care of him for her mother-in-law.
Season Two[]
He shows his competitive and commanding streak again by taking charge of an easter chicken army.
According to Barbara, he is a much friendlier dog than Monroe.
He likes telling stories about his adventures with Jasmine, and make people laugh.
He enjoys teasing Monroe about his weight.
Since it was hinted in Season 1[1] that it was Monroe who helped defeat Auntie Roon 400 years ago, it is possible that William already went to retirement a bit before 400 years ago.
