With Season 3 over, rumors are already circulating over Oliver's future allies and enemies.

That would be awesome to see them all.

If they're going to use Richard Dragon, I really hope they use the old version that trained The Question (who should also appear in his original form) and not the boring new one.

Also, am I the only one who doesn't want Diggle to become the Green Lantern? He's an original character. Don't turn him into John Stewart.

The one I don't agree with at all is the Red Hood. He's 100% Batman and there he should stay.
