Melissa Ryan (Presumably née Fenshaw) is Rachel Mason’s younger, sexier, bubblier sister. Her heart is in the right place, but her endeavours have a tendency to goof up as she has never really stuck anything out for very long. Classic sibling rivalry means that Rachel at once envies Melissa’s care-free exuberance for life, whilst Melissa believes she craves the authority and commitment Rachel has managed. Melissa left after her fiance, Eddie, discovered that she was already married to two other men, leaving her son Philip Ryan under the care of Rachel and Eddie. But later she returned to spring a surprise on Eddie, announcing that he was the father of her unborn child. Melissa is last seen leaving with Eddie, who promised to help raise their child.
