I'm A Mermaid And I'm Engaged To A Werewolf?!?!

Last time Scar was a normal girl with a normal firends, now this time Scar is back and she's a mermaid, engaged to a werewolf, and is having his child. What are they to do though when they have to lie about the pregnacy because a mermaid/werwolf child takes longer to be born than a human child does?
