Firstly I must say this episode was an emotional ball kick.
and now i have more of a reason to hate Scratch
anyway enough of me rambling
This episode raised a question for my where are the mallers?
-It sounds like they are in a hospital due to the medical equipment and doctors monitoring Angel (rest his soul).
-There are doctors which suggests that they are in a safe protected environment.
-The doctor not knowing not to mess with scratch hint towards the hospital not being somewhere where the mallers have been very long so it is possibly where they were all heading around chapter 20-22.
so this gives me two ideas of what it could be
-Firstly the could of gone to the colony which is an old theory but it has the fact that we know the colony does have medical facilities. however when we left the colony the only medical staff aside from nurses was Tania and she left with Michael and Co.
-Secondly this is an absolute long shot idea what if the are at Boulder? Colonel Kimmet did mention that Boulder has began a medical facility where new medics are being trained this is a long shot but who knows.
-Or they could be in a completely unknown location
these are just my ideas they could be completely wrong. feel free to comment and leave your own discussions and ideas
