Yay! Thank you!

I totally agree!

I wonder if they are going to make his "Feeling adrift" part of his issue for his own season.

if our suspicions about him being the focus on season 4 are correct, then it could be to see him float to contrast with him actually going for someone he wants more permanently in his life. We saw him in season 1 wondering about what was expected of him and what he wanted, we saw him go for something something he wanted (art school) in season 2 before he put it away when he found out Anthony had donated money to the school, here in this season we see him find out a bit more about himself and have some dalliances (call-back to the artists party he attended), and then maybe it could lead to him finding a love match in season 4. Going from seeing him float to seeing him strive - just like how we see Penelope go from finding some satisfaction from standing in the shadows to stepping into the spotlight with determination in this season.

A person who floats through life without a purpose or direction can feel useless and ungrounded. From my own experience, I can say it is miserable to exist in that aimless state. Relationships and work seemed pointless, even while I was in relationships (one of them a brief marriage) and working in the top positions of my prior career. I tried on multiple hobbies and said, "Why not," to anyone and anything that could potentially give my life meaning. Nothing helped to add that elusive spark to my existence. Eventually, though, my purpose finally arrived and after that my life became laser focused. Now, nothing, and I mean nothing, stands in my way-- neither my fears nor insecurities nor anyone. I foresee something similar happening for Benedict as the character is portrayed in the TV series. Someone is going to galvanize that man and set him on fire; then, and only then, will we see the real Benedict.
