Teen Wolf, Season 5

[Kira is trying to convince her father to put her sword back together]

Ken:
As your father, I'm obliged to warn you this is dangerous.

Kira:
As my father, I was hoping you wouldn't tell my mother.

Ken:
[smiles] That's dangerous, too.

Kira:
[sighs] I get it, Dad. I need to learn balance. I can't learn balance with the sword-- the sword brings out the Fox.

Ken:
You know it's more complicated than that. Learning balance is critical to controlling the Fox.

Kira:
What if the sword is critical to saving my friends?

Ken:
It's just a weapon, Kira. You're the critical part.

Kira:
I've got eight hundred years to learn balance. We need to help Mason right now. I need my sword.

Ken:
[sighs] It was forged with a unique power. It takes a certain power to put it back together again. You're going to need help.
