Obi-Wan is not physically demonstrative, but Luke is, and he's never truly gotten to say goodbye. Now, of course, he knows that goodbye isn't really goodbye, not for them. But still. He leans into the squeeze and then throws his arms around Ben, just one time.

But even in this dream, this vision, he is exhausted. His body battered, inside and out. And soon, he loses the concentration and either he or Obi-Wan fades from his consciousness, and he falls into a deep, dark slumber.

He's not sure how long he sleeps, but he awakes with a jolt, almost as if Palpatine has him again. His body is seizing, and while it lasts only a brief second, when it passes every muscle in his body aches with a vengeance only adrenaline had spared him the previous day. Everything hurts.
