"Twice now, actually," he admitted with an almost coy smile; having regenerated twice in only a few years was so typically him, and no one was more qualified to remind him of that than Romana. "Poor old Nine wasn't about for long at all. First one you've missed since Four, isn't it?" he commented with a sad smile. Given the circumstances, it was odd that he should feel sad about Romana having missed out on meeting his previous body, but he did.
Of course, he'd known the question was coming, but it didn't stop it being painful to think about. Slowly, he nodded, avoiding eye-contact as if he could somehow deny the guilt he'd carried for the past five years. "Only me. I was just..." he trailed off, shrugging. There was no way to explain it, and even though he knew that Romana would never need an explanation from him, he felt obligated to attempt one. "I couldn't save them. Not even... one," he admitted, his voice quivering slightly and betraying his attempt at a Gallifreyan exterior.
"The Master survived, by the way. He hadn't died, just like we thought. He'd used a Chameleon Arch to turn himself human and just... ran away. I found him recently," he explained; he had to tell her, ut he was worried about just how angry it would make her. She needed to know the truth, but unfortunately for them both, that truth wasn't exactly pretty. "He's dead, now. He refused to regenerate just to spite me," he went on with watery eyes and a shaking voice. "And I'm not exaggerating, he did tell me that was why."
