I had a hard time telling whether this was Natasha Romanoff or Maria Hill, tbh. But if you look at her belt buckle, it looks like Black Widow’s symbol, so I’m going to go with Natasha. Do you disagree? Discuss in the comments!
Maria Hill took the time out of her busy schedule to pose with the TARDIS. As an Agent of SHIELD, she is used to protecting Earth from the universe, and would probably get along fairly well with the Doctor. But that’s just my opinion. What do you think?
