Long-running character Carmel McQueen (Gemma Merna) was killed when the wreckage exploded after saving her cousin Theresa McQueen (Jorgie Porter) from "villainous" Sonny Valentine (Aaron Fontaine), who also died in the explosion, who wanted revenge on her for killing Calvin in 2010. Long-running character Mercedes McQueen (Jennifer Metcalfe) also "died" in November 2014, just a week after her sister Carmel, in a plot that saw her brutally murdered in the McQueen house by Grace Black. As of December 2014, only two original McQueen family members remain on screen, Myra McQueen (Nicole Barbara Lane) and John Paul McQueen (James Sutton). Mercedes returned in February 2015.
