Now Thea is on Team Arrow.
They got almost as many characters as Lost if you really think about it Oliver, Meryln, Thea, Diggle, Roy, Felicity, Laurel, Palmer, Detective Lance, and The chank couple. Multiple people need to die. Too many "heroes" and not enough villains. There needs to be just ONE sidekick. Speedy or Roy. Choose one. Laurel's storyline is really awful, she has like 2 weeks of boxing classes and she's out there w/ them and failing miserably becoming a liability. I get that its a comic book show but come on now.
Thinking back on it, "The New Batman Adventures" & "The Adventures of Batman & Robin" seasons of "Batman: The Animated Series" handled it right by making Nightwing & Batgirl recurring characters, while Robin was Batman's most frequent partner.
