So, the chances of Lokken being a true negative are only 25%, and there's another 25% chance he's just a character whose execution wouldn't matter much. And the remaining 50% in favor of him being a good guy prevent me from raising my hand against him. Overall, I have the impression that Lokken is either Charlie or is trying to imitate him.
As for Tox, you can really feel his extensive real-life mafia experience, even in his terminology. That's good if he's a good guy. But if he turns out to be a negative character with a failed assassination attempt, that would be a terrible disappointment. For now, I want to hope that he's a good guy...
