Parkinson has said that his fellow castmember Natalia Tena, who played Rickon's travelling companion Osha, helped him with his acting. He also shared what he believes Rickon went through after the death of his father Ned Stark, saying "After the death of his father, I think he became very independent and very angry, I think Rickon is a little bit more mature now. He's been away for quite a long time at this point. I think he's a bit more independent and stronger-willed.
