"Grandfather?"
He froze. Seeing off his wife, in a night that lasted decades, was one thing.
Running into her was another.
"...Yes. Hello, Susan."
"Look at you! I should go and tell-"
"The Academy taught you better than that."
"Grandfather, you're the one who told me to leave the Academy and come with you."
Yes, and how had that turned out for her?
"Can you at least say hello to Ian and Barbara?"
The thought of seeing them again made his hearts ache.
"I must be going...I love you, Susan."
He fled to his TARDIS before she could reply.
