It took a while for me to understand who deserves what exactly but last episode made everything more clear and this one made it crystal.
Since the beginning I've been trying to root for Ken because he's been introduced as the successor at first. Things were going back and forth between siblings, and I was still looking for a winner. Last episode made me think that it can be even Roman after he was pushed forward.
In the end, I came to a realization that this show is all about Logan. He's only using his kids powers and weaknesses for his own agenda and he's a master manipulator in that. In fact none of the siblings have the qualifications to be CEO yet he knows that they are his successors and he has to play the game, use them in the best way they serve him. In his mind, bunch of freeloaders who are not only satisfied by the wealth but also looking to take his throne.
However, Logan has a simple weakness. He doesn't want to win by referee decision, he wants a knockout, crushing his opponents. Therefore he plays too much with his hunt. This might cause unexpected turns if siblings realize the actual agenda behind it all.
Obviously balance between the siblings will constantly change as long as everything serves Logan's interests. Finally realizing it made the things more enjoyable for me. Looking forward to last two episodes and possibly the next season.
