Eh, dramatic license. I'm not too worried about that kind of thing if there isn't some kind of limited time element in play, which I don't think is the case here.
So things went all kinds of topsy-turvy. I'm not terribly surprised Kenny's death was ultimately an accident (assuming Konstantin is telling the truth). He didn't see important enough to be killed (despite his leads) and he was definitely not suicidal. The only thing I'm slightly surprised about is that his parentage wasn't brought up again, but I guess Carolyn wanted to keep at least that part private even when she was as harried as she was in that moment.
I loved the subway platform scene between Villanelle and her would-be replacement (I've already forgotten her name), knowing the scene would end the way it would, even if they didn't at the beginning. I especially loved the at the very beginning of the scene with Villanelle rocking back and forth on her heels in those ridiculous shows and her amazing outfit. So damn GIF worthy.
So now what? The Twelve only ever seemed secondary (at best) to the show's plot and the only leads they had are dead or tossed aside. Eve and Villanelle, no matter how much they both want to, they can't seem to walk away from each other. Neither of them wants their old jobs but they also have nothing else to do. So now what?
