Honestly, I don’t think that Anna was in any way, a ‘regular’ patient of Dr. Barrett’s. I believe, that Dr. Barrett was the ‘Psychiatrist’ on CALL when DANIEL died. I think he was the psychiatrist in the ‘closest vicinity’ and that is why he is the doctor that administered a sedative to Anna. Since he had ‘been there’ at the hospital when Daniel died, and therefore had ‘seen’ Anna before, it’s likely that he was ‘kept on’ as Anna’s psychiatrist aka ‘sedative giver’ until Daniel’s funeral was over at least! I would be surprised if Anna EVER saw Dr. Barrett prior to the night of Daniel’s death...or AFTER Daniel’s death, for that matter...
Daniel's funeral did not take place until 6 weeks after his death. Dr. Barrett supposedly sedated ANS right before the funeral (the day of) and afterwards also.
In addition, I would really LOVE to know what he heard ANS say about HKS and Daniel's death.
That makes more sense. I had a brain fart there.
