She didn't "blow the world up because she's sad" though.
I like the dynamic of Klaus and Five best, and I wish we could see more of it. Especially since I'm really into the twins theory.
Any time the siblings get to actually bond and act like siblings probably, and that they're all assholes on some level but none of them are bad people even if they've done bad things. Also Five telling Vanya "no one is insignificant" and Diego telling Luther "everyone changes the world" were great moments and also just really good messages.
I try not to get really into theories or prediction too much, but I do have a couple hopes for season 3. I hope they do a twins reveal, even if it's Luther not Klaus (that's a lie, I'll be so disappointed), and I think season 3 would be a good place for the siblings to discover something like that plotwise. I also hope that Ben doesn't actually change too much. Like he's not an evil *****, just slightly more ***** than the Ben we're used to because he didn't have the same positive sibling relationships he did in the original timeline. OR he's exactly the same as he was before he died because he does have positive sibling relationships with the Sparrows. Either way it's gonna be a wild time for the others. I just don't want him to be super different and for the siblings to comment on it/point it out that he's not that different than the Ben they knew.
I'm also on team "Let Klaus Snap". It's his turn to go feral.
Of course I hope Cody Ray gets to come back as Dave at some point, and we get to learn more about him and see more of his and Klaus's time together in Vietnam, even if it's not in season 3. And I want to see the siblings find out Reginald is an alien at some point, again not specifically in season 3 but generally.
