You should watch Arrow. It's not a bad show. Anyway, Damien Dark (one of the better bad guys they've come up with, mainly due to the guy who plays him) killed Canary a few episodes back, and now Arrow's aiming (snrt) to kill him outright. It has been known the entire season that Dark kills one of the cast, but the big question was who, and it was actually surprising that it was her given the close connection Black Canary has always had with the Green Arrow. I figured it'd be Diggle myself, but they've just wrinkled him by having him outright kill his brother.
