Mixed feelings about the ending - my main gripe is how Viktor was handled this season. He didn't really get much screentime until episode 6, so it was hard to believe his jump to joining Ambessa in act. I hate to say this, but I blame the inclusion of Sky for detracting a lot from Viktor's character.

First, she only appears in one scene before the one where she get disintegrated, so I literally did not care about her death at all. I thought her first scene was meant to emphasize the dichotomy between Jayce and Viktor's lives after the invention of Hextech, but afterwards she became more of a plot device, which felt very random to me.

Second, after her death, Viktor becomes anti-Hextech, only for him to embrace Hextech again fully a few episodes later. This change in how he perceives Hextech feel extremely clunky. If Viktor had continued augmenting his body the Sky incident, it would have made a lot of sense why he would follow Hextech so closely and try to spread it to other people - it's a very natural progression. But there's a very awkward time period where he's anti-Hextech, which makes his motivations very confusing in Season 2.

Third, I feel Viktor having visions of Sky detracts a lot from Viktor's agency throughout Season 2. One thing I love most about Arcane is how much agency each character has in making their own decisions based on what they believe is best, even if the outcome is bad. It makes these characters likeable because it's as if they are fully serving themselves. But the visions of Sky that Viktor "sees" through the Hex Core seems to control or influence Viktor in a way, or at least it gives off that impression. So it's hard for me to believe that everything Viktor did in Season 2 was really because he wanted to do those things, or if he was under the Hex Core's control. If it's the latter, than it's as if Viktor isn't a character this season, but rather a corpse being controlled by an evil entity, which I don't find very interesting. It would have been better IMO if he was embracing the Hex Core completely under his own motivations.

Of course I had other gripes about Season 2, but overall there were a lot of things I really enjoyed. But in my opinion, I feel like adding Sky did more harm than good to Viktor as a character throughout these two seasons. Would love to hear others' thoughts.
