These photos indicate clearly that Fanette and Fitzroy are friends. Very good friends. Did we really need proof? Look at the way they're staring fondly into each other's eyes.
They're a little reluctant, however, to let the wide world know that this relationship exists. They're modest. Maybe they themselves are not quite sure yet that it's a genuine love affair. Don't forget that even Kate and William spent a decade together before taking the big step. Meanwhile, Fitzroy has been edging cautiously his big wet tongue into the vicinity of Fanette's tender pale snout, and I wouldn't be at all surprised if actual contacts had already been made.
