Fan Casting Fifteenth Doctor (2016-2019)

Erin's first request was to go to a party, to which the Doctor decided to take her to the Wedding of Bastian Pagez, in 16th Century Scotland. While there, the Doctor and Erin became involved in the mysterious death of the Queen's husband, Lord Darnley. Despite intending just to leave, which the Doctor does do, shortly after she piloted the TARDIS back there, but two months later, not being able to resist the temptation to investigate. With the help of Bastian, the Doctor and Erin managed to uncover a larger conspiracy, including the Earl of Moray, Morton, William Maitland, Archibald Douglas, Lord Bothwell and the Queen herself. After they made it back to the TARDIS, the Doctor looked up what happened next and explained to Erin the sad truth about Queen Mary's life, prompting Erin to want to go home, for a bit.
