Characters of Casualty
Ash joined the hospital as a staff nurse and was promoted to senior staff nurse in series 7. When Lisa "Duffy" Duffin (Cathy Shipton) left the hospital, Ash became a charge nurse later on. He was suspended from the hospital when a racist thug that threatened him with a knife accuses him of assault, but was acquitted when Matt Hawley (Jason Merrells) admits he overheard the man threatening Ash. Ash continued his role of charge nurse until his departure. Ash returned to the ED in 2013 as a locum consultant, who was eventually given a permanent place within the hospital.
