According to a declaration filed by Natalie Graham, in support of Ariel's mother, Chrisoula Workman's attempt to re-gain custody of the actress after a judge gave temporary guardianship to the teenager's sister, Shanelle Gray, "I was very much so surprised at the relationship between Ariel and Cameron Palatas.
