donna first appears when billy mitchell (perry fenwick) spots her and trevor entering donna's house. a few days later, after much agonising over whether to tell little mo morgan (kacey ainsworth), trevor's wife, billy takes little mo to see for herself. on 28 august, little mo's sisters, kat slater (jessie wallace) and lynne hobbs (elaine lordan), reveal that donna is pregnant with trevor's baby. little mo visits donna several days later, and is urged by her not to let trevor hurt her any more.
