In Game of Thrones Osha is the girl who takes Bran Stark and Hodor on a journey to the Wall to find Jon Snow. She's an unexpectedly tough and sharp woman you definitely wouldn't want to mess with. You'll likely recognize Natalia Tena from the Harry Potter series, where she plays Malfoy's cousin Nymphadora Tonks, however, you can also check her out in the less known Bel Ami as Rachel.
