Thomas.

As with Mel and Marie and Annette, every good carnival has a seal-boy.  Or seal-girl.  Whatever.  People love people with deformities because it makes us feel better about ourselves.  Well, I suppose that's the reason some people do, I think others just want the shock value of a guy with a huge hole in his face.

Thomas W. Kavanagh

 Enter Thomas W. Kavanagh.  He was born with webbed feet and big flipper arms.  His father, a modestly successful day-trader with a huge degree of curiosity and acceptance, decided this was unusual and worth looking into.  He eventually discovered his quiet wife was actually a selkie and his own great grandmother was ALSO a selkie.  Now, common mythos says selkies are always female water spirits who wear a seal skin and can be tricked into living as a human if their skin is taken from them when they come onto the land.  Who's to say that a selkie might actually desire to live on land and take a human husband and have little seal-pup babies?  In my world, the combination of selkies within the family tree caused a short circuit.  Thomas wasn't born as human or selkie but a literal mix.  Because I like the idea of curses and what happens down the line if someone IS cursed.

Oh, and his middle name is Waits.  Because his father has a TERRIBLE sense of humor.  Also, he hates that joke.

And I realize I skipped a day in the posts.  But 26 is such a bad number!

Mythology is my dark mistress.
