"I bought a cactus from you, sort of."
Casey is the special someone of Beatrix back on Earth who will occasionally send letters to her via StarMail during the course of Adventure Mode, revealing some background information about Beatrix, Casey, and their relationship. Their gender is intentionally ambiguous. Note: to get the Casey letters (Re: Africa and beyond) you have to get to Hobson's discovery in the glass desert, then 1 pops up each day.
