The pilgrim cross springloaded blade...
Firstly - did a springloaded blade pop out the bottom of the pilgrim cross when the french guy was looking at it?
If so... why didn't he use it ever? That was the biggest gun on the mantel for me. He was even wearing it on the outside of his soldier suit when he went in to get the fuel cells from the alien ship, or whatever they were doing in there. It was the perfect time to stab something. Especially when the green dudes were popping up all over the place.
If not... what the heck was it?
