Arrow, Season 2

Diggle:
Doesn't exactly mean that Sebastien Blood is the man in the skull mask.

Felicity:
His last name is Blood. That can't be a good sign.

Diggle:

Felicity:
You're a personal bodyguard who fights crime at night with his billionaire boss. Not a lot of people show their real face in public.
