Mary Fulton was a nurse at Hope Hospital, acting as one of Derek Stiles’s key mentors, along with Greg Kasel, during the very beginning of Under the Knife and Second Opinion. She leaves after 1-4, as her husband receives a different job position, and is replaced by Angie. She makes a returning appearance in Trauma Center: Under the Knife 2.
Mary is a veteran nurse at Hope Hospital, seeming to have worked there well before Derek’s residency. She knows Derek very well, being able to tease him readily. She assists Derek in his first 3 independent operations after his residency. She quickly leaves, however, by 1-4, with her husband having found a new job in San Diego.
She makes a return appearance in Under the Knife 2, in order to help Derek regain his confidence.
Mary appears calm and well tempered throughout the games, and appears more collected and mature than her younger colleagues. In Under the Knife, she wears a pink nurse’s outfit. In Second Opinion and Under the Knife 2, she wears a white nurse’s outfit and has a mole on her right cheek.
Mary has a very likable personality, though she professes that she sometimes talks too much. She also enjoys teasing her colleagues during the games, revealing a more laid back aspect to her personality. She is, however, not afraid of taking charge of a situation, and demands only the best from her fellow doctors. Despite this, she offers unparalleled support in the operating theatre, as shown by her support of Derek Stiles during his loss of faith in his ability to preform surgery.
