Prologue
Their relationship was a complicated one. The first time they met, he had been 25 and attending the academy on Gallifrery. He was still well within his original body, years before he regenerated for the first time. She was teaching temporal mechanics at the Academy. It was her theory about time being a ball. Over the 150 years, he knew her for, his personality won her over as a friend. They never expected to meet again; most Gallifreyans chose not to regenerate as their original bodies could live to 200.
The second time they met it was at a bistro on Lulan VI. He was in his fourth regeneration and she teased him about his scarf. She got along wonderfully with Sarah-Jane and declined the offer to travel with them.
The third time they met was at the end of the Time War and he was in his eighth regeneration. She stood tall by his side, holding his hand while he blew up his entire planet. She was fully prepared to die by his side, and was just as surprised when the TARDIS saved them. She was at his side during his ninth regeneration. Once again, she declined to travel with him, but told him about an Auton invasion on Earth in 2005.
This is the story of their fourth meeting.
