I was just thinking about Oliver telling people to go to hell but someone says they are already there. Who is it?
Adrian Chase : Cecil Adams. You know him by his street name, The Count.You put arrows in him.
Oliver Queen : He was gonna kill a friend of mine.
Adrian Chase : Felicity Smoak. Yeah.

Oliver Queen : Go to hell.
Adrian Chase : I've already been there, Oliver, and I've come back with a message for you.
[fires 3 arrows at Oliver]
