I found it interesting nothing, and I mean nothing
was said about about the rest of the Fourth Doctor's companions, specifically Romana. I can understand holding off Adric, Nyssa and Tegan as they "belonged" more to Davison's tenure, but not to state anything about the one companion who could truly match or even exceed the Doctor's intelligence was a bit odd. Even if there are still ill feelings between Baker and Ward, they could have mentioned her first incarnation as played by Mary Tamm. Then again, if she were discussed and not Lalla, fans might have felt slighted, so maybe that's why the whole subject was avoided.
