The end of her life is chronicled in "A Death in the Family". A decade after her husband Rossiter died, Evelyn took part in an archaeological dig of alien technology, which resulted in her being accidentally transported to a planet called Pelicham, billions of years in the past. A few years later, Hex was dropped off on Pelicham after the Seventh Doctor died fighting a pan-dimensional enemy called Nobody No-One. Evelyn took Hex in as her ward for several months and told him about his mother, Cassie. The Doctor's other companion, Ace, resurrected the Doctor, and he travelled to Pelicham on the day Evelyn died of a heart attack. With her consent, he trapped Nobody No-One in her mind, and they died together.
