The Magpie's Nest

Honestly I think the telegram, then the subsequent realization that it was fake is a large part of why Hamid broke later in the episode. I thought Jonathan Sims was responsible for all the heartbreak in The Magnus Archives but I think it might be Alex. You don't tell us we won, tie it up in a neat bow, then not only go "never mind" but imply that the only time Hamid's parents ever said they were proud of him was in a dream sequence unless you actively seek out fan tears.
