That was Pete from Warehouse 13, right?
I thought it strange that the first thing May and Sif thought when they were talking about stealing nitrogen was "Maybe he needs it to breathe?" and "No, only 7 intelligent species require heightened levels of nitrogen gas." Isn't Earth's atmosphere 78% nitrogen? I mean, ya, it turns out that he didn't need it to breathe, but they first thought he did, and threw down the idea not because Earth already has heightened levels of nitrogen gas, but because only a few species actually need it...
