YMMV / Arrow S 6 E 15 Doppelganger

• Ass Pull: The Stinger — a League of Assassins member spying on Thea and Roy and reporting to her "master" that she has found the heir of Ra's Al-Ghul — comes completely out of nowhere and isn't connected to the rest of the episode at all.
• Broken Base: Black Siren being revealed as (apparently) The Mole for Diaz, mainly for fans who wants her to be redeemed. There are those who are disappointed since it appears to be just a Hope Spot now, while there are those who wants her Character Development to be gradual since an overnight Heel–Face Turn would make it look rushed and cheap. Then there are those content with it because they think redeeming her in the first place would be the wrong thing to do.
• Rescued from the Scrappy Heap: Downplayed. While fans still aren't on Dinah's side, many agree that having her work with Quentin and showing visible regret is the step in the right direction.
• Win Back the Crowd: Considering how polarizing last week's episode was, this one was much better received.
