So, you and Olivia have been mermaids for 3 years now! So one day you decide to go swimming! You go into the water in your pool and your mom goes, "hey honey you mind if I come in?". You...

  say , "Sure, go ahead!", your parents already know anyway.
  Glance at Olivia and nod.
  Scream no!
  Tell her that the water is freezing!

She ends up coming in anyway. She sees your tail. Quick...what do you do?

  She already knows!
  Tell her that you bought one from the store.
  Manipulate her with your song.

Your little sister (she wasn't in ep. 1 but she'll be here now), Marina, comes in. After a few seconds, she grows a tail too! What do you do?

  Scream
  Hug her! She's a mermaid with you know!
  Smile and show her yours.
  Nothing.

Your dad admits that he is too. He says that when you were born, there was a problem with your birth so you were human. Same with Marina. Marina admits to looking on your shelf and finding the book. What do you do?

  Yell at Marina for being in your room.
  Die from all the shock.
  Why didn't you tell me?
  ...speechless

Olivia was in the other corner of the pool, playing with her powers. She swam to you guys. You tell her the story. "Wow", she said. You ask to see your parents' and sister's powers. Your mom...

  Water powers, like you!
  Heating!
  Freezing!
  Jelly!
  Invisibility!
  Other!

Your sister's powers are:

  Water powers, like you!
  Heating!
  Freezing!
  Jelly!
  Invisibility!
  Other!

Your dad...

  Water powers, like you!
  Heating!
  Freezing!
  Jelly!
  Invisibility!
  Other!

You and Olivia show them your powers. "When did this happen?", mom asked.

  Oh recently...
  3 years ago.
  Last year.
  Just now.

Marina said she did it 3 months ago. So now you're a big, happy family of mermaids, and merman. You...

  Cry (tears of joy)
  Die
  Scream
  THIS IS AMAZING!!!!!!
