Every main couple has been involved in a love triangle. I don’t see them doing it again.
Neither do I, but not for the reason you gave. Simply, I don’t think the show will last long enough for a love triangle to happen again. But if the show goes on for more than the currently predicted six seasons, then it might. S8 comes along and with it comes some female pirate captain who tests CS or something. The writers fall back on and use the same storylines over and over (usually with a lot of self-plagerization) so if the show were to stay on air longer, then I think they’d totally do another triangle.
