"Serenity" is the twenty-second episode of Siren and the twelfth episode in the second season.

Summary Edit

Ryn goes back to the ocean to get help for Ben and Maddie's conditions as the lingering side-affects of her song, but discovers that continuing to go back may get harder than she realized the longer she's on land. From Eliza, they learn there may be a special place in Ryn’s homeland that may help. When one of them falls under the hypnotically soothing power of the siren song, this piques the military on how Ryn can be of use to them.

Meanwhile, Helen and Ted connect on their shared family histories, on whether or not Ted's relatives had a hand in the mysterious demise of Helen's father.

Quotes Edit

Bearded Man: "There. See that?"

Ian: "Wait. Looks like a person. "

Bearded Man: "A person in a place impossible to reach without gear. That's why they're sweeping this whole Eco-terror attack under the rug."

Ian: "Who is?"

Bearded Man: "The military, Man. I been working a Klesco for almost five years. Last year, they put away a tree hugger just for tagging a ship with a peace sign. They don't just let things go. '

Ian: "So you're telling me the United States military stepped in and is covering the attack on the drill ship?"

Bearded Man: "That's what I'm saying. Days after the attack, feds came in-swiped all the footage."

Ian: "Not all the footage."

Helen: "Well, according to this, my parents were staying in your family's cottage the night of the fire."

Ted Pownall: "Why would your family have been staying in our cottage?"

Helen: "Your guess is as good as mine. But this article says it was arson, which means my father was murdered."

Helen: "I'm just sating the facts! I'm sorry."

Ted Pownall: "
