Not to tell you how to do your vigilante-ing but the grease paint thing is a poor identity concealer.

Barry

Sebastian Blood: You know who he is under that hood, don't you?
Slade: I know exactly who he is. He's my friend.

I will arrange for you receive another sample of my blood, and then you can begin to mass produce the serum again.When I ask you not to confront the vigilante, you will listen. Remember, your mask can be worn by another.

Slade

I know I called you a murderer, but you are not. You are a hero. You beat the island. You beat my father. So fight, Oliver. Get up and fight back.

Tommy

The island didn't make you strong, kid. It revealed you to be weak.

Slade

Oliver: You're dead.
Slade: You're not a hero. Or a friend. Or a brother. You're nothing.

Oliver Queen. He is a billionare by day and saves the city by night.

Barry

Barry: Don't worry, I'll find out what's wrong with Oliver.
Felicity: You'd be the first.

So find me a mask that conforms perfectly to my face and doesn't affect my ability to aim while I'm on the run.

Oliver

Shado: I had to see you, to warn you.
Oliver: Warn me?
Shado: You can't fight what's coming. Put down your bow. Take off my father's hood.

Never meet your heroes, right?

Felicity

Oliver: You told him who I am.
Felicity: Yeah, I did.
Oliver: That's not your secret to tell, Felicity. I decide who finds out my identity.
