Snape looks so very much at home in this environment. I've never bought into the fancy of an Italian-descended Snape, but I could certainly agree here that he's clearly made a new home for himself in this warmer clime.
The thing that says it all is how he's wearing only his vest! That glimpse of underarm hair says he's totally comfortable letting finicky fangirls see his OMG hairy-male-hairiness in a way he never was at Hogwarts. I love how his activity pulls it up a bit to show his middle!
Take me with you there. I'm sure they need visitors! We could, y'know, do the house-elfing or raise healthy nommy vegetables for them or something. Like, sell tickets. ;-)
