I'm enjoying the show still, and I like seeing young Smurf. I'm fascinated by her past and how she got where she is today, as well as seeing the men in her life when she was younger. I feel it breaks up the current plots nicely and it's cool to see the connections between past and present.
With the fisherman scene, what I took from that was Smurf reconfirming to herself that men (I'd say people, but I think Smurf has a different vision of men than women) will do anything for money even if it's cruel, and also that she is still an effective manipulator. At first when the fish was suffering, the fisherman was going to stun it so it wouldn't suffer. But she made it clear that he was getting the money for allowing the fish to suffer and die while he just stood by and did nothing. And so he did, he took the money and did nothing. I wonder if he'd refused the money, stunned the fish, or anything else maybe she would have felt less in control of things, but it reconfirmed her manipulative effectiveness and her way of life. YMMV.
