So Komodo isn't the killer... and Merlyn's been training Thea all this time, so I doubt it was him. Unless he got word that Sara was sent by Ra's to find him, and made a pre-emptive strike against her. But that wouldn't really explain why Sara was so surprised and off guard when she saw him, so I think it's probably not Dark Archer. Aside from that, not a very big list of suspects left
.
As for Komodo himself... well, he was an effective antagonist and certainly gave Oliver a run for his money, but I was expecting a little more from him. Lacroix seemed like an interesting guy once he started talking, so hopefully he makes a return later in the season
.
His final fight with Arrow and Arsenal at Queen/Palmer Industries was pretty cool though
Also, is it just me, or did the Arrow-Cycle look more green in this episode
?
Considering how integral and major Sara was to Team Arrow, it only makes sense that her death would take a big toll. Oliver was left unable to grieve for the lover whom he'd never been able to get proper resolution with, and now never will, all for the sake of the rest of the team. And now, after beginning to believe he couldn't be Oliver Queen anymore, Oliver finally realizes that he doesn't want to give himself to the crusade so much that he ends up dying alone and in the Arrowcave
.
The stress of Sara's death, and seeing how Oliver had to deal with it, has also seemed to have caused Felicity to begin rethinking what she wants to do with her life and led her into the fold of Ray Palmer who still swings from being a lovable jerk to a lovable nice guy
.
Diggle has always been an awesome bro, but he went above and beyond here, coming back to the team to help support them through Sara's death and being there for Oliver when he really needed someone. While Arsenal will probably remain the main field partner for Arrow, Diggle being there as both backup and as a backbone for the team will probably be even more crucial. It was also very heartwarming of him and Lyla to name their daughter after Sara
.
Tommy in the flashback was also an awesome bro, going all the way to Hong Kong because of the possibility that Oliver might still be alive. It was just really nice to see Tommy again. And I guess that was the first time Oliver used the "Arrow-voice," or at least what it's like without the vocoder?
Sara's death seems to have effected Laurel in the worst way possible, barely able to control her emotions and coming close to breaking down now that she's lost her sister again and seen her die in right in front of her eyes. All the more reason to take lessons to toughen herself up, both to make her a stronger person and to put her on the path of inheriting her sister's identity and becoming Black Canary. Well, likely minus the fishnets, but at least she'll have the jacket
.
Now that I think about it though, shouldn't someone tell Sin that Sara's dead? That seems like something Roy should do, plus he could use a love interest now that Thea probably wants nothing to do with him.
