Arrow can’t just be pecks and eye candy for the ladies. The show has to be held together by a action, plot and pecks. Another regular character to expect in season 2 is Amanda Waller. She has made appearances in Smallville (Pam Grier) and Green Lantern (Angela Bassett).
My first pick for casting would be CCH Pounder, but she is busy with Warehouse 13. Another solid choice is S. Epatha Merkeson. Who do you think should be cast as the White Queen?
