@Xandermcc - I immediately thought the man in the iron mask was the real Jay Garrick when he tapped the name Jay and got distressed when Barry said he was alive, believing Hunter was Jay. Then when we learned “Jay” was really Hunter Zolomon I believed it even more that it was the real Jay Garrick. While there are other Vigilantes in the comics none of them have shown up at least yet so I’m just speculating within the realm of what’s established.

@TheDoctor230 - Lyla mentioned Cayden was apprehended 8 months ago. The Wild Dog back-story episode, 5x13, when Oliver briefly encountered Vigilante again was the same episode Curtis suggested the lawyer for Rene for custody of his daughter which Quentin stated in this episode was 2 months ago. The timing doesn’t work out so Cayden isn’t Vigilante. As for Adrian being Vigilante and Prometheus but was next to Oliver, maybe Adrian wasn’t really there? If you watch that scene carefully nobody looks at Adrian during that scene.

@Stryzzar - If Vigilante isn’t Adrian pulling some double identity trick I think it’s Roy Harper, as Vigilante really reminds me of Red Hood and since Arrow steals from Batman all the time Roy would most likely get the Jason Todd storyline. Why he would try to kill Oliver I don’t know.
