 It turned out that Toni and Dominic's mother Ngaire Thompson (Ilona Rodgers) had an affair with Bruce Warner back in the mid 1970s and that Ngaire had Bruce's child.Margot initially feared that Toni was that child (meaning that Chris and Toni's affair had been incestuous) but Dominic had allayed her worries by revealing that he was in fact the product of Bruce and Ngaire's affair.Margot had always felt that Dominic had been deprived (particularly since Bruce had accepted his other illegitimate son Guy) and so left him the money in her will as a form of compensation.
