Don't like Trouba - but good for him and his wife. You negotiate yourself a NMC - and this is certainly one valid reason to make use of it.
That being said - the article says "It is not as if Dr. Tyson-Trouba can pick up, transfer her credits to another hospital, accompany her husband and still be licensed as a physician."
I mean....couldn't she? I have to assume there are ways to do this, if they wanted to.
