Summary: The Doctor has something that doesn't belong to him.
“If you didn’t steal the sacred seal of Mirrabeau, then how do you account for it being in your possession?” The official glared at the Doctor from beneath bushy black brows. “It’s kept in the most secure vault in the kingdom!”
The Doctor glared back from beneath his own, rather greyer, eyebrows. “If the vault’s that secure, then how d’you think I could have stolen it in the first place? Anyway, I didn’t know what it was. I found it in a little shop in Vervax. Thought it made a nice key fob. Are you sure it’s not a replica?”
