Many years ago, I was calling around to try to find a therapist. I spoke to one and told her I did not want someone who would tell me what to do. Based on that, she concluded she couldn't work with me. Always felt I dodged a bullet there.
I didn't particularly enjoy this episode.
It's been mentioned upthread a couple of times, but it doesn't make much sense that Kate is still morbidly obese in the scenarios where Jack lives. We were previously led to believe that Jack's death is what led to her enormous weight gain, although this season it's seemed more like Marc's abuse is where that trajectory starts. If Jack had lived, it's unlikely she would have met Marc.
I don't know much about clinical trials, but my understanding is that one cannot simply just decide to participate in a clinical trial. Not to mention, she may not get the experimental drug. Since Rebecca is at the cabin in August, she clearly doesn't end up spending 9 months in St. Louis.
Either way, adult Randall has a history of manipulating others to get what he wants, but this instance is really beyond the pale.
