Trivia

 * This episode takes place 92 days after Crisis as takes place 90 days after the event (which the later episode starts right after the previous one). As Kara states the events of the 's ending scene (the opening scene of this episode) is in the same days' morning, it is safe to assume that this episode takes place 2 days after  and therefore makes it in mid-April.
