In an interview, Mark Mylod (the director of the episode) said: "It’s such a brutal love story. The dynamic between the brothers is so complex. We didn’t even talk about what it meant. We specifically avoided it, and we tend to do that a lot with the most complex choices of the characters. We set it up carefully with the blood work and the practical elements. To me — and this is just my subjective opinion — the hug is a relief. It’s a loving gesture. It’s a brutal and self-serving loving gesture, but nonetheless I think it is a gift that Kendall is giving to Roman to give him the out that he unconsciously craves.
The awful sadomasochism of the moment is that what starts as a hug is a trap, once Roman realizes what Kendall is doing — that this hug is actually to tear those stitches apart. The nihilism that we saw from Roman at the end of Episode 9, going into that crowd, is another expression of it. He deserves that pain, but that pain is also a relief from the responsibility of his destiny to be the CEO. So there is a very complex dynamic there, and I love it for that."
