This was a hard question for me to answer, honestly. I love Alice and Jasper so much, the way they are so completely in sync with one another is fantastic. BUT, I have to say my most treasured couple would have to be Carlisle & Esme.
They may be the best parents EVER who've never actually given birth to their children. They are endlessly supportive, loving and kind to everyone. They are a true embodiment of happiness and that's kind of hard to compete with in my opinion.
If anyone saw “favorite vampire” posted earlier this month you can all probably guess who my favorite couple is (even though Alice and Jasper almost made it on here for me). It is...
…Rosalie and Emmett.
Because honestly, they’re perfect for each other. Emmett is fully devoted to Rosalie and I have no doubts about that; she’s his entire world, and makes it obvious, more so than any other couple in this entire saga (*cough*Bella/Edward*cough*). And Rosalie is a much better person with Emmett; he brings out the best in her, and after the past she’s been through, she deserves someone to treat her like a queen.
They are by far my favorite couple; for Twilight and probably just in general, all fandom’s considered! They’re just perfect. :3
MY answer is simple! Alice and Jasper! Holding hands in the car in twilight; the airport in New Moon (which didn’t make it into the movie &*&^%); “You never have to be that person again.” In Eclipse……… they are soul mates and it’s evident and I love that! Their dance scene in BD1 was greatness; they compliment each other perfectly in every way in every book.
