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

(Maybe Grayson learned how to impersonate her while they were both working on That Darn Cat. [ghost_grin])
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. [ghost_wink] (Well, unless they tell us.) So, it's not necessarily true that anything in PT shares the limitations of RT. (Or even the advances...)
