Yes, they're human beings, they have feelings.
As I said before, my issue with Season 4 isn't so much that the crew talks about their feelings all the time, it's that the crew all has basically the same feelings, and they all talk about their feelings in exactly the same way.
Pretty much every heart-to-heart over the course of the season could be exchanged between any two random characters, and it would play off almost exactly the same way.
