And this second one is about Zip too. In Legend, the dialogue about the PDA device, how it wouldn't work if Lara ate it or something. I was like "Whaat?! Why would she do so?" I still wonder what's it about...
Zip was talking about the fact that you have to wait an hour after eating to go swimming. As I recall, he said she could swim with it no problem, then added the comment about eating it. It was a joke he made. I thought it was quite funny, too.
