I wasn't a fan of this episode.
I found Oliver's recovery to be implausible. To be fair, there may be more to his recovery than what has been seen on screen. But, I don't believe that Tatsu who, from memory, has not been shown to have any medical skills in the flashbacks, could heal Oliver after he suffered multiple stab wounds and injuries from a significant fall with some secret herbs and spices.
I also found Laurel's vigilante activities to be implausible. Again, to be fair, they showed that Laurel was having a hard time living up to the Canary's reputation. But, I still found it implausible that she would go up against multiple assailants armed with guns and survive thanks to some self-defence and boxing classes. The fact that she was using Sara's fighting staff with no confirmed training in that weapon was absurd to me. I also think that she got off very lightly with just a few scratches and bruises, despite being badly beaten by brick and then jumping out of a window!
If they'd kept Laurel fighting common street thugs for the moment as she learned additional skills, then it would have been somewhat plausible. But, having her go up against Brick and his hand-picked crew who he sprung from imminent jail because of their skills in thuggery was a step too far for me.
The Merlyn and Thea scenes just don't interest me. I'm bored with Merlyn's "mystery" mission and intentions and Thea's continued ignorance about Merlyn's manipulations annoys me. After all her anger about being lied to, I'd expect her to be a bit more proactive in ensuring that she's surrounding herself by people that she can trust. I also find it hilarious that, from memory, Merlyn is surely known to most residents of the city as the master-mind behind the disaster in The Glades, yet he's freely wandering around the city without any fear of being recognised. Sure, he's presumed dead by the public (again, from memory), but running around in expensive suits, limos, etc would surely arouse the curiosity of a lot of people on the street, whether regular folk or a journalist or police officer.
