That last hug, the one in Truth Be Told, seems the current favorite, and perhaps for good reason, it's the first time Oliver is the one needing the comforting, and is one in a series of indications that the script, has indeed, flipped. Let me explain.
The Treasure Box
Truth Be Told
These three hugs demonstrate the arc of growth these two have undergone. Shane has become a stronger and better partner for Oliver, and Oliver has become more vulnerable and has looked to Shane to lean on.
A subtle indication of their growth, it's pretty much my favorite---ShOliver hugs are the best, hands down!
By the way, have you seen that extended trailer for The Impossible Dream yet?
