Outlander transports viewers to the past every episode with its opening credits featuring "The Skye Boat Song." And the journey continues with the Outlander title cards that give a glimpse of what's to come in the episode. Just like how the opening credits evolve season to season, the title cards are customized for each and every episode and they provide Easter eggs for book-reader fans and non-book-readers fans alike.

The title card is when the episode's name is shown and for Outlander, it nearly always features a hint to one of the episode's main plots. Fans who have read Diana Gabaldon's books may pick up on the meaning of the title card imagery a little quicker than TV-only fans, but some are harder to crack than others. Thankfully, those behind the scenes often help fans decode the title cards' meanings.

Beyond the images changing each episode, Outlander composer Bear McCreary wrote on his blog in September 2014 that he also changes the music for each title card by using different instruments that match the theme of the episode. But to go over all of the musical clues would require a whole separate article. So here are all the visual Easter eggs in the 67 Outlander title cards so far.

Season 1

Episode 1: "Sassenach"

The blue forget-me-nots at Craigh na Dun are what cause Claire to return to the stones by herself, where she is subsequently transported back in time. Some fans even theorize that Jamie's ghost had a hand in planting those blue flowers to lure Claire to the past, so they are incredibly symbolic to the fandom and the perfect way to establish the meaning-filled title cards.
