Arrow “Canaries” Canadian Promo Trailer Gives Very Big Things Away (SPOILERS)

For whatever reason, international outlets cut their own promos for shows sometimes, and in doing so, give away different, MAJOR plot points.

Case in point: The Canadian CTV promo trailer for next week’s Arrow, titled “Canaries,” which gives away that thing we thought might have been given away in the promo images.

Needless to say, you’ve been warned about spoilers. Our thanks to “Molly S” who put it on YouTube… and to the CTV promo editor who might not realize “hey, that’s a very big deal.” Unless, as “BoldOutlaw” pointed out to us on Twitter, the whole thing is a Vertigo-induced hallucination.
