Arrow returned with a really good episode. Two break-ups! I loved the tension that was building throughout, both between Ollie and Digg and Ollie and Tommy, and actually felt pretty sad for Tommy. He's been a good friend to Oliver, but I'm sure a dark path beckons.
J. August Richards was pretty cool as the assassin. It's a shame he died because I'd like to have seen more of him. I loved the fight in the Queen mansion.
The visit to the morgue in the police station was sick and I loved Thea and Roy's reactions to Laurel's dad poking the corpse with the arrow. I thought the motivation for Roy wanting to track down the vigilante was pretty cool too.
The island stuff was minimal but seems pretty important. Good cliffhanger.
