Stovka shows what Barry's life could turn into if he continues murdering for Fuches. Stovka laments that his whole life has been death at the word of his masters. He's a ghost of a man at only 45 and takes his own life rather than continuing his wretched existence. Fuches is even blamed for driving him to kill himself. Barry never meets him and thus remains in Fuches' thrall until much later.
The Season 2 premiere showed a terrifying glimpse of Hank's dark side when he chillingly warns Barry to kill Esther or else he'll out him as Goran's killer. Considering that he's a remorseless criminal mobster who plans out tortures and murders despite that fact that he's not an inherently violent person, what is he like when he snaps and is pushed over the edge? Will it be similar to how Barry is like or will it be much worse?
With Ronnie now dead, Lily is still out there in the city all alone and possibly still feral...
Season two suggests Sally might have an abusive streak. She is a sweet person, buried under layers of anxieties, self doubts and her own abuse trauma, but her behaviour towards Barry at several points in season two is problematic at best. She ignores his profound discomfort over taking part in her scenes, guilt tripping him into performing with her. Despite him literally begging not to take part in the language and violence, she resorts to verbal and physical abuse to goad him into right emotional reaction, in front of their friends, while justifying that she's 'helping' him with the scene and then in the next breath admitting she took it too far. She can't help but undermine him constantly and on the night of the final showcase, when Barry is clearly emotionally disturbed by something, she just hauls off and slaps him. On both occasions she could (and does) claim she's helping him get into the scene, but on both occasions she is also anxious and frustrated, meaning there is real anger when she strikes out. Made all the more troubling by the fact they are a romantic couple by this point, and she is a far more dominant personality than he is, adding another, uncomfortable dynamic to her behaviour. This isn't just two actors getting 'intense' for the work, this is a girlfriend striking her boyfriend because he's not giving her what she wants.
