I have to admit that Green Arrow's type of vigilante justice is a bit disturbing. He was channeling his inner Snidely Whiplash when he chained the guy to the railroad tracks. He also impaled the bad guys hand with an arrow. The cop figured out his secret identity already? That was fast. Are there reasons why he isn't referred to as Green Arrow on the show yet? So I guess that stepdad finding the salvaged yacht means that Oliver's mom knew where Oliver was for at least some of the five years he was missing.
