So maybe True Blood‘s Ryan Kwanten not having a clue about co-stars Stephen Moyer and Anna Paquin’s relationship wasn’t necessarily his fault. Turns out their other co-star, Sam Trammell, had not a clue, either!

In a post-Emmy party, Trammell, who plays the shapeshifter Sam Merlotte on the hit vampire show, revealed that he didn’t see it coming: “I think they’re both just really independent, really talented people, and they just kind of fit together… They’re so professional, I had no idea they were together at first. And then I had no idea he’d proposed to her.”

Don’t count on fiction meshing with reality here—Sam, whose character is in love with Anna’s Sookie despite her relationship with vampire Bill (Moyer), has nothing but good wishes for the newly-engaged: “They’ve been together a long time, and it’s working out. I’m happy for them.”
