Since i'm not quite done writing stuff, I just gotta throw down another post. Absolutely loved the season finale, and really love the different pieces they are setting up for Season 4. S3, for me, rebounded on some of the issues I had with S2 & then some. There is just so much to unpack with what happened this season.
My favorite development, though, has to be the reconciliation that occurred at the very end of the season. It turns out Elliot has been doing the right thing (taking down the people who are in control of the world for their own ends) for the wrong reason (revenge), but it wasn't such a simple revenge story. In Elliot's mind, his dad having been the one to push him out a window has been viewed as a result of the trust Elliot broke when he told his Mom about his father's condition. By extension, Elliot more than likely held a deeper grudge with E-Corp as they were the ones to blame for his father's condition, which led to his father doing something so horrible to him in the first place. And this grudge was something young Elliot hung onto deeply, as we see in this season when we watch how Elliot interacted with his father right before he died.
But Elliot now knows the truth - his father never pushed him out that window. When he now sees Mr. Robot, he doesn't have to see the man who hurt him as a child anymore. Its pivotal that this revelation occurred right before Mr. Robot & him fully reconciled & agreed to work together as a team from then on. This should give Elliot, and subsequently Mr. Robot, the ability to pursue DA/WR without that blinding lust for revenge clouding their judgement, which is what got them & the world the mess they found themselves in in the first place.
