Cleo and Kim are concerned when it seems that their father has found a new girlfriend. With no desire for a step-mother, the girls are horrified when their father invites the woman over for dinner; but Cleo is even more horrified to discover that she is Charlotte's mother. Feeling that desperate times call for desperate measures, Cleo invites Rikki and Emma round, and persuades them to use their powers to ruin her father's dinner. Only afterwards do the girls realise their mistake; Charlotte's mother was a business associate of Cleo's father, interested in buying some of his catch.
