Let me start with a small introduction of both characters:
Kate Heightmeyer is a secondary character who appears a grand total of 5 episodes out of 100, while Teyla Emmagan is one of the main players. Kate’s the resident psychologist, and member of the Atlantis expedition sent from Earth to find and explore the lost city of Atlantis in the Pegasus galaxy. Teyla’s a member of a Pegasus tribe, known as the Athosians, and forced to flee her planet when the main antagonists of the expedition, the Wraith, attack the tribe. She joins with the team in order to gain the upper hand (if at all possible) against theses Wraith.
And after the intro, we continue...
The first time we see both of them together is in the season 1 episode, The Gift, in which Teyla discovers she has some Wraith DNA in her genetic make-up, which explains why she can sense the Wraith coming. Kate, as the psychologist, helps her deal with this gift. And when it’s discovered that Teyla is capable of connecting with the telepathic network of the Wraith, Kate helps her through that as well.
Kate meets Teyla in the cafeteria, but encounters a bit of stubborness when she tries to offer her help to the Athosian. Teyla isn't in the least bit interested in Kate's offer, and shows this rather strongly.
As soon as the ice is broken, she helps Teyla in dealing with her new found abilities to connect with the Wraith.
I immediately noticed a natural chemistry between both characters. Kate obviously cares about Teyla’s well-being, which later develops in what could be seen as a good friendship between the two women. Of course, I like to think there’s more to it than just friends.
The great chemistry can partially be attributed to the real life friendship between the two actresses and it shows on screen.
Of the 5 episodes that both characters can be seen, there are only 3 where they have scenes together. And of course there's Doppelganger which effective immediately puts and end to the on screen time of both characters in later episodes because it holds the untimely demise of Kate, who is killed in her sleep by an alien life form which invades people’s minds to terrorize. When Kate dies we witness the devastation in Teyla as she looses a dear friend, though obviously I’d like to think it’s again more than just a friend. This last episode is the height of the relationship, but also the end of it.
And we come full circle - the place where Teyla and Kate got to know each other the first time, is the place they'll be together the last.
Teyla's the one to find Kate dead in her bed.
The loss of a lover can tear a heart to shreds.
However, the Nile isn’t just a river in Egypt and thus I happily continue to ship them to my heart’s content. I love this pairing because they fit together so nicely. They might be opposites in character, not even of the same galaxy, but they complete each other perfectly.
