It’s an interesting one. I really liked that first scene, because while Alexei has a point - being a freelance murderer for the CIA is a terrible career and Yelena would be better off trying to do something more altruistic and less nihilistic with her life - he also has the wrong end of the stick, in that he conflates being a hero with getting fame and glory.
But Yelena does at least talk to Valentina about changing her work conditions to involve less crime and murder, and it’s actually Valentina who uses the term “public-facing” to mock her (and thinking Yelena won’t notice because she’s too stupid because she’s just some gig economy assassin, not management like her), while of course planning to have her killed, because what’s the point of a Doordash murderer who isn’t really into murdering any more?
And then the tables turn and Valentina needs someone to pretend to be a hero for the cameras, and Yelena and the Thunderbolts will do for now. That’s not necessarily what any of them actually want (OK, maybe Alexei and John are super into it, but I doubt Ava, Bob, or Bucky actually love it), including Yelena, but at least she’s doing some version of what she’s good at and she’s doing some good, so hey, why not. It’s not her happy ending, it’s a work in progress.
