St Luke's courtyard

The courtyard was a location on the outside of St Luke's University's main building.

Upon arriving at the university, Bill Potts saw the Twelfth Doctor and Nardole running through it. She secretly followed them, until they arrived at a mysterious vault. Bill accidentally made a noise, so she left.

On her way back to the campus, she met Heather, and approached her. They began chatting, until, eventually, Heather took Bill to look at the weird oil puddle. (TV: The Pilot)
