 You know how much I respect the military so this isn't a slight on anyone there. Notice however, whenever the colonel was contacted by the doctor (including at the very end) he'd always say something to the effect of "Will this take long, doctor? I've got an appointment." Whenever the doctor would say "It's about Hatcher" the colonel would nonchalantly say "oh, him."

It's likely the colonel was indeed a very busy man. However, this served to set the tone for how (seemingly) insignificant Hatcher's life really was in this episode.

I definitely picked up on the "oh, him" comment and wondered if the colonel wasn't more involved in the destruction of Kent's mind. During the initial stages of the RMT plays, I find my mind searching for the possible story lines and the "colonel as a sinister character" plot certainly crossed my mind.

At the end, the inscription on the inside of the bracelet - I am unsure how this plays into the story. Obviously, the mother would have known what it said and no one else would have. So, there we have a mystery in and of itself but how does that connect to any other events? We were not supposed to believe that Kent was her son - that would not make sense. His name was known. So, what is that all about?

With the bracelet inscription being correct and Kent having a name similar to the woman's son, I was sure the author was going to turn this into a "mother reunited with her son" story.
