What affected me most were the scenes with John being overpowered by strangers and medicine shoved down his throat, later being forced back into his wheelchair, and still later with his leg in a cast and using crutches.  It made me wonder what dramaturgy O'Quinn has explored to create the layers of his character.  I enjoy his story arc so much, I'm sure because I identify so deeply with his pain, bitterness at being confined to a wheelchair, and his passionate determination to be physically in control of his destiny.

Terry O'Quinn is such an easy actor to watch.  He fully inhabits Locke, and even though I felt like the producers were rushing through this episode and smashing me with assault after assault without giving the episode enough room to breathe, O'Quinn slowed his moments down with his breath and focus.  

So, a brutal episode, but an episode that reaffirms O'Quinn's talent and confidence as an actor. I keep thinking about degrees of pain, the relationship between physical and psychic pain and the cleansing nature of pain, and this was a timely episode.
