Here are the Sand Snake ladies (Keisha Castle-Hughes, Jessica Henwick and Rosabell Laurenti Sellers) in costume on set preparing to shoot a fight scene which is rumored to include the character’s of Jaimie Lannister and Bronn. The 3 eldest Sand Snakes are the bastard daughters of the late Oberyn Martell. In the book there are 8 of them, but only 3 have been cast.
Plus, we have a snap of Peter Dinklage (Tyrion) which was taken at a hotel in Osuna, Spain.
