Ep 8 – Point of No Return

DAYS 15 – 26

One might presume that the timeline continues as before such that Episode 8 picks up the same evening or night as the previous episode, similar to other episodes. However, after the flashback to Flight 828’s landing on November 4, 2018, episode 8 continues with a scene in which both Ben and Michaela are wearing different clothes than where they left off in episode 7 which suggests that these scenes do not occur on the same day.

Morning/Afternoon (Weekdays)

  1. Olive goes to school and soccer practice.

DAY 27

Since this is Cal’s first day of school, this suggest a time jump has occurred (see above). Since most of episode 8 occurs within an 18 hour time frame (cf. 108.3), and since Vance later states that the plane had come back three weeks ago (108.22), and the fact that episode 9 takes place on a Saturday, that brings Cal’s first day to Friday, November 30, 2018.

Ep 10 – Crosswinds

DAYS 29-37

According to Michaela, it has been 10 days since the last calling (110.3), that means the events of episode 10 occur on Monday, December 10, 2018.
