Airborne

.. as in altitude when they return from an international conference in Singapore. On the plane one fellow begins projectile vomiting. At first House is just annoyed that this is happening across the row from the first class seat he finagled. But soon it becomes a race to solve the man's mystery illness - he does not speak English and seems to be traveling alone - as it has all of the classic symptoms of bacterial meningitis which is very contagious, very deadly, and it is a very long flight. He has to do this with literally no medical instruments and only the medication he can cajole out of the other passengers.

Meanwhile, on the ground, a 58 year old woman has returned from a vacation in Venezuela that she took on a lark - sex, drugs, rock and roll, a last hurrah you might call it. She would have been born in 1949, so heck, maybe she was at Woodstock. She is demonstrating a host of neurological symptoms and the Houseless team has to figure out things on their own, complicated by the fact that Chase and Cameron are having a sexual relationship, he wants it to be more, she does not, and it is influencing their work performance. Two comments - Am I the only one who noticed that the cat's food bowl was full? Watch and find out what I mean. And, yes, Foreman, there is such a thing as just sex. Go ask the stashed plate club and they will agree with me.

I really liked how this was presented with the intercutting between scenes in the two crises. A very excellent episode, as usual.
