Pete and Myka however are a terrible example. When the two leads on Warehouse 13 are both in real relationships simultaneously for more than a couple episodes, then we can start talking about definitively established Platonic relationships. .
I don't know. It's been four seasons and the show really hasn't gone there.
And I can testify to the fact that, when I was writing my WH13 novel, the show's writers and producers were emphatic about the fact that I was NOT to imply any sort of romantic connection or chemistry between Pete and Myka. I was specifically instructed to go for more of squabbling siblings vibe . . . .
(Besides, we all know that Myka is in love with Helena!)
