The things he promised himself he'd never do.
1) Never fall in love with a companion
2) Never bend the laws of time so far they break
3) Go back to Gallifrey
Well, he was having a rather productive Saturday, wasn't he?
He watched Romana sleep for a long while and eventually left the bed to make them some tea. It wouldn't be so bad, once she got over the shock and the breaking of the timeline and the destruction of her home world...
He sighed as he put the kettle on. He should never have gone back. Never have pulled her from what she knew. But then again, if he did she'd be dead. And he couldn't lose her, not after everything.
He grabbed some toast and the tea and headed back towards his bedroom. She'd wake up soon (one could only hope) and at least she'd have some breakfast ready.
