His buddy, who wants to handle exolife in the middle of a tomb where the most prominent characteristic is everyone died under mysterious circumstances, pushes past the bounds of credibility.
The silly thing is you didn't even have to write the scene that way to get the same effect. He could have taken every procedure and still gotten killed. I think there was an element of the writer wanting the audience to react with a very visceral 'don't do that you fool!' But it didn't work.
I've got no problem with David experimenting with Holloway. I felt that was completely appropriate.
