Margaret Stubbs is a primary school teacher who lives in Holby.
On 8 September 2007, Margaret injured her back whilst picking up after her dog and visited Holby City Hospital's emergency department for treatment. However, when a major incident was declared, and all non-urgent patients were sent to another hospital, she stayed behind so her son could find her. Senior charge nurse Charlie Fairhead, the father of one of her former students, found her on the mezzanine and went to get her some codeine and diclofenac. However, she later went into anaphylactic shock and collapsed on the stairs. (CAS: "Charlie's Anniversary")
