Somebody Is Going to Die!!!

Quentin had a lot of potential as the Jim Gordon type character, but like so many of the others they jerked him around to much and lost direction for him. They should have kept him on the force, though it's hard to say if he should have eventually become commissioner, which might have been too much like Gordon. The idea of him becoming Mayor had some merit; and could have given him a similar dynamic with the Green Arrow, while making him functionally different. Plus I think it would have been better than Oliver serving as mayor, at least during the time he did.

In hindsight, I think Lance should have been kept in the dark about Oliver's identity; maybe even Laurel's. How they would have dealt with Sara or Laurel's death, or how Sara came back or Black Siren is hard to say, but I think once he out and out knew, that marked a distinct shift; where there seemed to be very little pretense about his secret identity, and at that point or soon after all of the main characters knew who the Green Arrow was. And the show wasn't the same any more.
