You took the Unbreakable Vow
Before you knew what you were doing
Can you keep a secret?
Can you keep a secret?
You promised you'd help him
Did you even know the plan?
Can you keep a secret?
Can you keep a secret?

Whose side are you on?
Don't you dare look at me
Whose side are you on?
You're listening at keyholes

Making notes in the margins
Of a book you left in class
A non-verbal called Sectumsempra
What sick mind thinks of that?
Turns out your not the only one
Who sold out the Potters
Every time we turn around
Another traitor is revealed

Whose side are you on?
Don't you dare look at me
Whose side are you on?
You're listening at keyholes

Whose side are you on?

Where are your half-blooded principles?
