I'm glad Digg is now in on the secret. I hope Deadshot isn't dead, even though it's pretty hard to recover from an arrow through the eye. I did love the sound effects of the arrows in the final battle, they sounded like fireworks.
The voiceovers are beginning to annoy me, I hope they phase them out. The present day adventures are a bit routine, I hope they make the villains more challenging and I'd like to see an episode which has more of an emphasis on the island.
I'm betting the arrow didn't penetrate through the eyepiece into the eye, but just knocked him out.
He probably came too while the others weren't looking.
