Taking some moments to ponder, Leela sipped her tea. "I am uncertain what could send him to Romana. Perhaps just talking about her? If he has plans that include her, or if he has truly changed, then perhaps that is enough to pique his interest? I have noticed he has been hiding lately, not making himself known. It is worrisome." Because only bad ever came when the Master kept a low profile. It usually meant he was plotting something, and Leela really wanted to keep Romana from getting hurt whenever that would happen.
After falling silent, Leela looked back up at the Doctor. "Doctor, is it possible to mend a friendship when trust hangs by a thread?" She was talking of her friendship with Romana, and she hoped the Doctor would be able to give her some advice in how to proceed. Aside from K-9, the Doctor was the only person she truly trusted anymore, and it saddened her. She didn't want Romana to lose her trust, but she was having a hard time closing wounds when she wasn't even sure how to talk to Romana anymore.
