Riley (The Thirteenth Stone)
From Tardis Wiki, the free Doctor Who reference
Mr Riley was the curator of the Stone Whisperers. Sarah Jane Smith found him to be very boring. In 2008, he gave Mr Bradbury's history class a tour of the exhibit when they visited it after their field trip. Mr Riley was locked out of the exhibit during Luke's mental battle with Ravage.
