“Take me with you.”
The Doctor read determination in Luke’s young, too wise eyes. “You should go to university. Be with your mates.”
“What am I going to learn in university? I can teach most of the courses already.” He stepped closer, his voice intent. “Mum’s not always going to be here, and I need to be ready to take over for her. Teach me what you taught her. Teach me how to save the world.”
“She won’t like it.” But he could tell she knew what they were discussing and what his answer would be.
“Alright then. Come on.”
