* Our introduction to the antagonist: because Frank didn't die, Julia was able to save a dying patient. But the ominous music and the way he opens one eye gives the very strong implication that something ''evil'' has awoken...
* With John's dream (as the timeline changes again), the audience is led to believe that it's a remnant memory of his father's funeral before the changes in the past. [[spoiler: Then we find out it was his ''mother's'' funeral instead]].
* In a rather frightening case of WhatMightHaveBeen, Frank [[spoiler: gets caught by Shepard (the Nightingale killer)]] while trying to protect the nurses and almost becomes a victim himself. It's only by the grace of two hippies interrupting Shepard that he was spared.
** The broken record playing Phil Phillips' "Sea of Love" when Frank walks through the murder scene of one of the nurses: ''"Do you remember wheeennnn w-Do you remember wheeennnn w-Do you remember wheeennnn w-"''.
* In the altered timeline, the implication that [[spoiler: Shepard murdered ''his own mother'']].
* When Shepard finds his way to Frank and Julia's room...while Julia thinks he's Frank.
* Shepard's [[spoiler: hand getting shot off in the past and thus necrotizing and withering away to nothing in the present]].
* While we know what's really going on the whole time, the first contact through the radio is quite disturbing from Frank's point of view, as a strange man suddenly contacts him, is unusually knowledgeable about his family, and finally states that he can ''see'' how Frank just burned his desk.
