Eh. I just don't understand what the producers/writers are intending for this season.
It was great that Oliver told Thea that she killed Sara. But, why doesn't he just tell her EVERYTHING instead of still holding onto some secrets (i.e. the videotape of the murder and Malcolm's extreme manipulation of Team Arrow). And is someone now going to tell Laurel who murdered Sara so that she knows, and can tell her parents, the complete truth?
And Slade was wasted. They could have developed his character, but he was instead still "crazy" and obsessed with Shado's death. That's really poor motivation for what is otherwise a compelling character.
I also remain extremely confused about Malcolm's plan. The League of Assassins suspected that Malcolm was alive and had various assassins, including Sara, out searching for him. The LOA wanted Malcolm dead because of his role in The Undertaking which violated the LOA's principles or the orders of Ra's or something or other. So, the LOA had already issued a death warrant for Malcolm.
Malcolm decides that the best way to protect himself from the LOA is to manipulate Thea into caring for him as her father. Once Malcolm achieves this, he then drugs Thea and forces her to kill Sara. The LOA then want to find and kill Sara's murdered because she was a member of the LOA, even though Ra's seems to consider her membership to be tenuous at best and she primarily seems to serve as Nyssa's consort rather than a truly active assassin (at least after she rejoins the LOA).
Apparently Ra's is too stubborn to listen to reason and will kill Thea even though it is pretty clear to anyone and everyone that Malcolm manipulated the situation. So, the LOA now issues a death warrant for Sara's killer which is revealed to be Thea. Oliver assumes responsibility for Thea's role in Sara's murder to protect Thea. Oliver doesn't reveal Malcolm's role because apparently Malcolm will "protect" Thea while simultaneously threatening to reveal a video of Thea murdering Sara which will reveal the "truth" to the LOA (and possibly also have Thea arrested by the police).
For some extremely unclear reason, Malcolm believes that Oliver will be able to kill Ra's. This would mean that Oliver is no longer responsible for Sara's death and is free from the LOA. But, I don't see how that would absolve Malcolm of his death sentence. Surely Nyssa or whoever else assumes leadership of the LOA would still execute the death warrants on everyone else the LOA is hunting?
And it really doesn't make sense for Malcolm to believe that Oliver has the skills to kill Ra's or that even if he did have the necessary skills, that he actually has the "killer instinct" to kill Ra's. Oliver is good, but he's not that good, especially when not in his element (i.e. the city) using his best weapon (i.e. the bow and arrow).
So, Malcolm must have suspected that Oliver would die, which would "settle" the debt of Sara's death (although I find it difficult to believe that Ra's would truly accept Oliver's death in place of the real killer, unless he cared so little about Sara that he just wanted to punish someone for her death and move on). But, that wouldn't free Malcolm from the LOA's sights. The LOA would still be hunting Malcolm for his role in The Undertaking.
I guess Oliver's death could have resulted in Malcolm permanently joining and leading Team Arrow, but I'm not sure the assistance of Diggle and Roy (and Thea) would help Malcolm to kill Ra's.
And I don't understand what the LOA is planning. They had two primary goals - kill Malcolm and find and kill Sara's killer. They seem to be extremely poor at achieving their first goal. Malcolm is running around Starling City and hanging out with his daughter on a regular basis, but despite sending DJ Assassin to watch Thea, the LOA don't locate Malcolm? And instead of finding and killed Malcolm, Ra's apparently changes DJ Assassin's orders and tells him to kill Thea (only after seducing her of course). Did Ra's order DJ Assassin to kill Thea because he knows the truth about Sara's death? If so, it would explain why Ra's didn't immediately come after Oliver when Oliver (as the Arrow) revealed that he was alive and back in Starling City. But, if Ra's knew the truth about Sara's death, then why didn't Thea get a duel to the death like Oliver did. And why wasn't Thea immediately murdered instead of the drawn out "death by romance" tactic?
As for Malcolm's videotape, I'm surprised that Team Arrow is working on something for its release. Is Malcolm intending to send it direct to Ra's? In which instance, I guess Team Arrow couldn't really prevent it, but they could at least compile evidence of Malcolm's involvement. Of course, now that Ra's has apparently decided to kill Thea anyway, does it really matter what happens to the videotape? I guess if it's released publicly, then Daddy Lance and Laurel Lance may come after Thea seeking "justice", but I'm not sure Thea could actually be charged with murder given that there is no victim and the whole videotape looks like some kind of bizarre prank/stunt, especially with a third person filming it. I don't see the Lances trying to kill Thea, no matter how angry they may be about Sara's death. I guess Daddy Lance could dig up Sara's body and somehow explain that they now have the murder victim so Thea can be charge, but he'd also have to explain how and why his supposedly dead daughter actually died 7 years after her first "death" and why she was running around in a mask on the rooftops at night.
As for possible public humiliation following the release of the videotape, I'm not sure that really matters. Felicity could surely devise some magic techno solution which would erase all copies of the video. Or she could produce a bunch of alternate versions showing all sorts of people in place of Thea and Sara and basically make out that it's one big internet prank/stunt/meme.
And I'm still not following Malcolm's plan. I don't understand why Oliver is still agreeing to work with him. So, Oliver knows that the LOA is coming up Thea and presumably Malcolm. Couldn't he try to capture Malcolm and offer him to Ra's? Thea no longer cares for Malcolm, so he doesn't have to worry about "losing" Thea emotionally. By delivering Malcolm to Ra's, Oliver could try to reason with Ra's about Thea's involvement in Sara's death. In that situation, Thea was really just the gun, but it was Malcolm who loaded the gun, aimed it and pulled the trigger. I would have thought that it is at least worth a try as the alternative is to continue "training" with Malcolm, although that training seems a little bizarre as Malcolm is yet to actually train Oliver so I'm not sure what Oliver is learning from the "student" which will help him to kill the "teacher".
Anyway, maybe they'll turn it all around in the final run to the close of the season.
