Tate: Donna Return Unlikely
Speaking in a Guardian webchat earlier today, she explained why: “Unfortunately I think Donna’s storyline would prevent her from coming back, because any memory of the Doctor, of her time travelling with him, and the adventures she embarked on, would kill her. So I can’t see a storyline being able to bring her back.”
However Tate is full of praise for Capaldi: “I think Peter is wonderful in the role, and I’m really enjoying the 8th season. He’s a fantastic actor, and his wit and intelligence shines.”
