Is it just me, or does Hoffman look like she's channeling Elsa Lanchester in this capture:

That Darn Cat.
)
And as for the tests - never forget that this is PT, so we have no idea what type of tests are available there or what doctors can and cannot discern.
(Well, unless they tell us.) So, it's not necessarily true that anything in PT shares the limitations of RT. (Or even the advances...)
