Question: Who was younger the year Grace accidentally cut her finger off, Christopher Hobbs or Mark Ferguson? Passage:Following the departure of Simon Hilton-Jones (John Wraight) from Shortland Street clinic, Chief Executive Officer Michael McKenna (Paul Gittins) decided to poach Grace from his rival Sir. Bruce Warner's (Ken Blackburn) clinic. Bruce was devastated to hear Grace was leaving and made a hugely public announcement of his love for her in the Kennedy's bar, to which she rejected him. Grace began work at Shortland Street though her naturally flirtatious manner led many to believe she was having an affair with both Bruce and Michael - even Michael's wife Alex (Liddy Holloway). Grace dated Darryl Neilson (Mark Ferguson) but soon came to realize he was stealing her eggs and selling them off, leading to a break up. She subsequently had a brief relationship with Zac Smith (Mike Edward) but ended up deciding to flee Ferndale after reconciling with Darryl. However Darryl's dead body was found in the Auckland harbor. The following year Grace fell in love with Lionel Skeggins (John Leigh) but instead took up with Minnie's (Katrina Devine) father, Ryan Birch (Robert Harte). However she soon came to realize Ryan had in fact raped her best friend Ellen (Robyn Malcolm) several years beforehand and they broke up. Grace finally got together with Lionel but the romance was short lived and she moved onto Frank Malone (Christopher Hobbs). In 1997 whilst cooking, Grace accidentally severed her finger however luckily managed to reattach it. Shortly after, Grace got a job in Australia and departed Ferndale. The following year, Ellen visited Grace and returned with the news that she had become a mother to two twin boys. Grace returned to Ferndale in October 2013 to audit the hospital following the CEO, Chris Warner's (Michael Galvin) health concerns. It soon transpired that Grace had been through a devastating break up and was in desperate need to be a mother. She made an agreement with Chris that would see the two have sex without complications so as to have a child. Grace then realise that she has feelings for Chris and then tried to stop his wedding to Rachel McKenna. She then leave Ferndale after Chris couldn't return her feelings and she leaves after she lied that she had a miscarriage.
