Melissa Ryan 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 but later returned to spring a surprise on Eddie, announcing that he was the father of her unborn child.
- "First things first, my name is Melissa. You can call me that, or Mel or whatever you feel comfortable with, just not Ms. Ryan please, it makes me sound like a lesbian dominatrix."
